Intune: Automatically set timezone on new device build

In Michael Niehaus’ recent blog on Configuring Windows 10 defaults via Windows Autopilot using an MSI he talked about the ability to set the Time Zone of the device based on a variable in the Config.xml file. One of the comments on the blog asked whether it would be possible to set the time zone based on where the device was at the time of setup rather than based on an attribute in the file.

Whilst Windows 10 has a feature to detect the time zone automatically I have found on occasion with devices that this doesn’t always work out of the box and the time zone remains in a region that is not accurate for where the device is. This should be relatively simple to automate if we can geo-locate the public IP address and match those coordinates to a valid time zone. For this I am using two web services:

  1. https://ipstack.com – this will map the public IP address to a geo-location including coordinates, you get access to 10,000 queries a month for free
  2. Bing Maps API – this will return the correct time zone in a valid Windows format that can be used in the script to set the time zone on the device, there is a free tier here that also gives you 10,000 queries per month without charge

The Script

The script will execute the following in sequence:

  1. Attempt to get the coordinates of the IP address you are using via the IPStack API
  2. If successful, attempt to find the time zone from the Bing Maps API
  3. Compare the value of the current time zone on the machine with the response from the Bing Maps API
  4. Change the time zone on the machine

The only variable you should need to change in the script are the two lines that will contain your API keys helpfully called ipStackAPIKey and bingMapsAPIKey.

You can choose now to either save the file as a script to run once in Intune, or, incorporate this into Michael’s MSI. If you wanted the script to run every time the machine starts up, you could adapt the Logon script from my recent post on Mapping legacy files shares for Azure AD joined devices.

The script will output to a folder in %PROGRAMDATA% called Intune-PowerShell-Logs.

Hopefully you will find this useful to configure time zone information on your Modern Workplace machines.

Mapping legacy files shares for Azure AD joined devices

More and more of my customers are moving their devices from a traditional IT model to a Modern Desktop build directly in Azure AD, managing devices via Microsoft Intune rather than Group Policy or System Center Configuration Manager. The move to this modern approach of delivering IT services usually sits alongside of moving the organisation’s unstructured file data to OneDrive and SharePoint online which is the logical place to store this data instead of sat on a file server in an office or datacentre.

What if, however, that you still have a large volume of data that remains on your on premises file servers. Users will still require access to these shares but there is no native way of connecting to file shares within the Intune console. This is the challenge I have had for a customer in recent weeks and have developed a couple of PowerShell scripts that can be run to map drives when a user logs in and supports both dedicated and shared devices.

The Challenge

Looking back at a legacy IT approach, drive mappings were done through either Group Policy Preferences but also through login scripts such as batch or KIX. Both processes follow a similar method:

  1. User signs into a device
  2. GPP or login script runs containing list of mapped drives aligned to security groups of users who should have access
  3. If the user signing into the device is in the relevant groups the drive letter is mapped to the shared location

This method has worked for years and IT admins maintain one or the other process to give users access to corporate data. If we now look forward to the modern managed IT environment, there are a few issues when working with the legacy file servers:

  • There is no native construct in Intune that maps UNC file paths for users
  • Whilst you can run a PowerShell script that could run a New-PSDrive cmdlet this will only execute once on the device and never again.

You may think that the second piece isn’t an issue, simply create a couple of scripts to map the network drives to the file shares and they will run once and remain mapped. What if the devices are shared and multiple users need to sign into the computer or if you need to amend the drive mappings? We needed a solution that could map drives at user sign in and be easy to change as the organisation moves away from file servers.

The Solution

As with most things, I started looking at what was on the Internet and quickly came across these blogs from Nicola Suter and Jos Lieben but neither really did what I needed for my customer (they have >100 different network drives). I set about looking for scripts that would deliver what I needed for the customer.

My requirements for the new drive mapping script were as follows:

  • Work natively with Azure AD joined devices
  • support users on dedicated or shared workstations
  • process the drive mappings sequentially as a traditional GPP or Login script would execute

Let’s start with the actual drive mapping script itself

Drive mapping script

For the drive mapping script to work, it needs to run silently and also enumerate the groups that the user has access to. Sounds easy, but PowerShell and AzureAD doesn’t natively have a way of matching these. I settled on making use of Microsoft’s Graph API listMemberOf function as this can be called to pull the groups that a user is a member of into a variable that can work with the drive mapping. The function requires a minimum permission of Directory.ReadAll which needed to be granted through an App Registration in Azure AD. Step forward my next web help in the form of Lee Ford’s blog on using Graph API with PowerShell

Configure Azure AD

First sign into Azure Portal and navigate to Azure AD and Application Registrations (Preview) to create a new App Registration. Give the app a name

Create new App Registration

When its created you will be shown the new app details. make sure that you note down the Directory ID and the Application (client) ID as you will need these in the script.

App and Directory ID values will be used in the script

As well as these ID values, you also need a Redirect URI that is referenced in the script, click on Add a Redirect URI and choose the item in the screenshot below then click Save.

Now that the app is registered, we need to add permissions to read data from Graph API. Click on the API Permissions heading to grant the required Directory.ReadAll delegated permission.

Add the Directory.ReadAll permission to the App Registration

By default the user’s making a connection to the API will be required to consent to the permissions change. To make this seamless, we can use our administrative account to grant this consent on behalf of all organisation users.

Grant Admin consent

This is the setup of the Azure AD Application that will be used to access the Graph API, we can now focus on the PowerShell script that will map the drives.

The Drive Mapping Script

The Drive mapping script is made up of several parts:

  • Configuration section where you setup the Application Registration and drive mappings that will be run for each user
  • Connection to the Graph API
  • Enumeration of group membership for the user
  • Iterating through all drive maps and mapping those that the user is a member of.

I will share the script in full further down this post but have included the key snippets in each location.

First we define the variables for the app registration we created earlier.

Once these are in place we setup our array of drive mappings. In this section there are four attributes that can be defined:

  • includeSecurityGroup – this is the group of users who should have the drive mapped
  • excludeSecurityGroup – this is a group of users who shouldnt have the drive mapped (this is optional)
  • driveLetter – this is the alphabetical letter that will be used as part of the drive mapping
  • UNCPath – this is the reference to the file share that should be mapped to the drive letter.

The code in the script looks like this:

You can add as many lines in the $Drivemappings variable as you have groups that need mapping, just make sure that the final line doesn’t have a comma at the end of the line.

Next we create the connection to Graph API. I use the code from Lee’s blog earlier and it worked first time:

Now we need to use the token we generated and query the Graph API to get the list of groups that our user is a member of

Finally we need to check if the user can see the domain (there’s no point executing the script if they are out of the office) and for each group the user is a member of, map the drives using the New-PSDrive cmdlet

That’s it, the script when executed will run as the user and map the drives. We now need to host this script somewhere that can be referenced from any device with an Internet connection.

Uploading the script to Azure

We will host the drive mapping script in a blob store in Azure. Sign into your Azure Portal and click on Storage Accounts and create a new one with the following settings

Once created we need to add a Container that will store the script

and finally we upload the script to the container

Once uploaded we need to get the URL for the script so we can use this in the Intune script later.

The Intune Script

Now that we have our drive mapping script and its uploaded to the Azure blob, we need a way of calling this every time a user signs into the computer. This script will:

  • Be run from the Intune Management Extension as the SYSTEM account
  • Create a new Scheduled Task that will execute a hidden PowerShell window at logon which will download and run the previous script

The only variable we need to change in this script is the URL to the drive mapping script and the name of the scheduled task that is created. The whole script looks like:

This now needs to be added to Intune so that it can be executed on the devices. Navigate to Intue, Device Configuration, PowerShell scripts and add a new script

Once the file is uploaded, click on Configure to check how the script should be run

Once complete click Save and the script will be uploaded.

Finally we need to assign the script to users or devices. In my example all my computers are deployed via Autopilot so I assign the script to my Autopilot security groups which contain all the computer accounts.

The end result

When the Intune script runs on the endpoint it will check if the scheduled task exists and whether the script it will execute matches what was in any previous configuration. If there is no task, it is created and if there are changes, the old task is deleted and a new task is created.

When a user signs in they will see a popup window as the auth token is generated and then, if they are connected to the corporate network, their network drives will be mapped.

If you need to change the drives that a user has access to (either as you migrate to a more appropritae cloud service or you change the servers that host the data) simply amend the script in the blob store and the new drives will be mapped at logon.

The Intune script can be re-used for any other code that you want to run at user logon, simply reference the link to the script in the blob store and the name of the scheduled task you wish to use.

Remove additional languages from Windows 10 after 1803 upgrade

After I completed a recent upgrade of Windows 10 to 1803, I noticed that my English (United Kingdom) language had been joined by English (United States) and that I couldn’t remove this from the system.

After a bit of research I came across the following article that demonstrated how the additional language can be removed using PowerShell – https://answers.microsoft.com/en-us/windows/forum/windows_10-other_settings/unable-to-remove-a-language-from-windows-10-april/47c13ea5-79ed-4a29-96d4-47d1264b6838

Nice and cleanly I no longer have the “ENG” menu in my task bar to switch to a language I don’t need.

PowerShell software installation wrapper for Intune

A lot of my work recently has been working with Microsoft Intune to utilise Microsoft Modern Management constructs and principles to deliver a cloud first approach to provisioning new Windows 10 endpoints for an organisation.

Since Microsoft has migrated Intune management from the classic interface to the Azure Portal, the ability to execute installers for legacy line of business applications has been reduced. The idea is that the modern workplace is consuming data via apps from an app store and this is evident in Microsoft’s support for the Microsoft Store for Business and Universal Windows Platform .appx package support in Intune however this is not always feasible in most workplaces. There are still legacy line of business applications that require an MSI or EXE based installer and whilst Intune will support Line of Business installers that are MSI based there is again a limitation that the MSI must contain all the code required to install the application. There is currently no support for EXE based installers in the Azure Portal for Intune.

Back at Microsoft Ignite 2017, Microsoft announced the availability of the Intune Management Extension and the support to execute PowerShell scripts on Windows 10 Endpoints via Microsoft Intune (Read More). This got me thinking about how to extend the functionality of Microsoft Intune to deliver a more traditional (MDT / SCCM) provisioning process for legacy applications on modern managed Windows 10 devices.

If you could store your legacy line of business applications in a web accessible location (with appropriate security controls to prevent unauthorised access) you could then utilise the Intune Management Extension and PowerShell scripts to download the application install payload to a temporary location and then execute the payload to overcome the limitation of the Intune portal.

Looking around the Internet I came across this blog post by MVP Peter van der Woude which integrates the Chocolatey package manager and Intune. With a bit of reworking I amended the PowerShell code to download and install the AEM agent onto a target machine.

Save the PowerShell script and then add to Intune as outlined in Peter’s blog post and wait for the code to execute on your endpoint. The process can be extended to run any executable based installer.

Whilst this is a fairly simplistic example, the concept could be extended to download a compressed archive, extract and then execute the installer as required.

Microsoft Intune – Android Apps

As I deploy more and more instances of Microsoft Intune I am having to  onfigure managed applications for Android and iOS enrolled devices. Whilst the iOS app store has been neatly integrated into the Azure portal, Android apps need to be added by their relevant App URL (frustrating and something I hope that Microsoft / Google can fix in the near future).

When configuring the mobile app and app protection policies it can be useful to have the correct Microsoft suite (Outlook, Word, Excel, PowerPoint, OneDrive, Skype for Business etc.) installed automatically on the end user device. The list below is hopefully a time saver to get to each of the applications without having to click through or search the Google Play store manually:

Reporting on inactive AD user accounts

In the second quick article following my reporting requirement this time is to report on the enabled user accounts that have not logged in in the past X days. Again a quick Google came across the following article on WindowsITPro (Use Get-ADUser to Find Inactive AD Users)

I took the Search-ADAccount cmdlet and created some filters to exclude disabled accounts as well as enable a parameter to be passed with the script to specify the maximum age, in days, of a user account (default is 90 days)

Save the below script as Get-InactiveAccounts.ps1

To execute the script run .\Get-InactiveAccounts.ps1 to report on accounts older than 90 days or use the InactiveDays parameter to specify the age of accounts to report (eg .\Get-InactiveAccounts.ps1 -InactiveDays 180)

Reporting on AD users last password change

As part of some recent work to assist a client with reporting on their active users and the dates those users last changed their passwords I evolved a script written by Carl Gray here (PowerShell: Get-ADUser to retrieve password last set and expiry information) to generate a short PowerShell script that will report the enabled Active Directory users and the date that they last set their password.

Copy the code below and save on your server as Get-PasswordLastChange.ps1 and then run from the command line. Script will produce a CSV file and save it in the same directory as the script

Enabling DirSync for Office 365 after decommissioning Exchange

I have been working on an issue for one of my clients where they have migrated email from an on-premise Exchange server to Microsoft Office 365. The migration was handled using a third party migration tool to synchronise email content into their Office 365 tenant, something that didn’t go smoothly and not wholly relevant to this posting. The major thing that wasn’t fully setup was the synchronisation between their existing on-premise Active Directory and their 365 tenant and users struggled initially with passwords that were not in sync between the two platforms. One thing that did happen however was that the Exchange server was decommissioned and any Exchange attributes removed from the Active Directory user accounts.

Looking into this I started by upgrading the installed version of DirSync to the latest release from Microsoft (click here) which automatically detected the previous installation and upgraded it to the latest release. As described in upgrade guide I completed the initial configuration and provided the following to the wizard:

  • Office 365 administrative login,
  • my Active Directory details,
  • the fact that it is not a hybrid deployment (remember Exchange has already been uninstalled),
  • that I wanted to sync passwords and
  • to not perform an initial sync (I need to troubleshoot what hasn’t been working).

I opened the not so easy to find Synchronisation Service Manager (C:\Program Files\Windows Azure Active Directory Sync\SYNCBUS\Synchronization Service\UIShell) and checked the configuration of the data to be synchronised.

We are synchronising our users based on their location in Active Directory and have created two Organisational Units (OUs) under two separate User OUs within our directory only one of these has been selected at this stage.

The user was showing up and the synchronisation log was showing success messages. I updated the Department attribute for the user within Active Directory and forced a sync to office 365, no errors reported in the Sync Manager and the Office 365 user was updated correctly. This seemed so simple so I informed my client we would enable the changes this week and everything would go back to one password and, apart from the shortcoming of Microsoft Outlook not participating with the Single Sign-On that the rest of Office does, users would be happy.

Or so I thought until I came to actually enable the remainder of the users…

I opened Synchronisation Service Manger, browsed to Management Agents and edited the Active Directory Connector, edited the Containers I wanted to sync and clicked OK only to be given the message:

Join/Protection validation error
‘publicFolder’ is no longer listed in the list of selected object classes

Googling didn’t come up with much more than this forum post (https://social.technet.microsoft.com/Forums/en-US/f3cfc3f1-4dac-4f33-b036-399e6c57fd10/dirsync-joinprotection-validation-error?forum=ilm2) which was unanswered at the time.

Looking through the options I found that under Select Object Type the publicFolder wasn’t listed so after clicking Show All, scrolling down a long way I enabled it and was able to save the update configuration

publicFolder Object Type

First hurdle out the way I moved a user into my new OU and forced another synchronisation… which failed

Attribute Value must be unique

Clicking on the error I was redirected to a Microsoft KB article (KB2647098). Reading through the article I knew there were no duplicate accounts either locally in my AD domain or in the 365 tenant so I started to look into the proxyaddresses to see if Exchange had left something in place when it was removed from the network. When I looked in ADSIEdit at the user in question I found there were no proxyaddresses listed at all:

Checking the one synchronised user I noticed that they did have the proxy addresses listed so I added them manually in the format

SMTP:Firstname.Surname@domain.com
smtp:samAccountName@domain.com

Saving this and re-running the sync gave me a success, my user was now showing as synchronised with Office 365. I added another couple of users but this time, when I synchronised I received a different error message

ds11

I checked the accounts were enabled both in Office 365 and in Active Directory, restarted the DirSync service to no avail. After looking at this and a handful of other users I could see that this was going to take a while to complete manually so needed to automate this in some way. Rather than spend some time researching how to write the appropriate PowerShell commands to complete this change I switched to my trusty friend ADModify.net (https://admodify.codeplex.com/)which I have used many times in the past to update attributes in bulk within Active Directory.

For those of you that haven’t used it ADModify.net is a very competent tool at modifying the attributes of a number of AD objects in bulk.

Extract the contents of the download and run the executable then click on Modify Attributes when prompted

ds6

Select your Domain and preferred Domain Controller from the menu on the left, click the green icon and then browse to your OU to modify.

ds8

Click on Add to List at the bottom to add the discovered objects, select the ones you wish to modify and click on Next

ds9

On the email addresses tab choose Add SMTP Address and enter the email address in the format you want to use. Set Primary and update the General tab as well then click Go.

At this stage the tool will update the AD attributes for the list of objects selected earlier, output a popup with the status of any failures as well as write an XML based log file to the directory the executable ran from. Review any errors and then continue to add any other addresses

ds10

Here I have added an address that matches their UPN login to match the configuration I can see for my Office 365 users.

Now that these have been run against all the AD accounts that need to synchronise I restarted the DirSync services once more and completed my sync without issues.

The conclusion from all this is to make sure that everything is in place to synchronise your Active Directory and Office 365 tenant *before* decommissioning Exchange but also that if you are in this situation that you make use of tools such as ADModify.net to save the hassle of editing all the records by hand.

New Job, Updated blog

After eight years working at Wavex I have taken the decision to move on for a new career challenge and I am now a Senior Infrastructure Engineer at IT Lab. The past eight years have been a very good learning experience and I have developed from a young and inexperienced Service Desk Engineer into a more confident and technical IT Professional with the ability to communicate on a technical and commercial level to explain the problem and solution in a given situation.

As part of this change I have decided to try and remove some of the more juvenile aspects of my website and tidy up some of the blog posts that were written before I started my professional career as I realised that many of these were inappropriate content for a modern audience. All the blog content has moved from the subfolder “blog” to the root of my website and I am hoping that as my new role develops that there will be new content added over the coming months to read.

Thank you to all those at Wavex for their time in the past and here’s to the future.
