Migration phase 3 - client-side configuration
Relevant for: AIP unified labeling client and classic client
To provide a unified and streamlined customer experience, the Azure Information Protection classic client and Label Management in the Azure Portal are deprecated as of March 31, 2021. No further support is provided for the classic client, and maintenance versions will no longer be released.
Use the following information for Phase 3 of migrating from AD RMS to Azure Information Protection. These procedures cover step 7 from Migrating from AD RMS to Azure Information Protection.
Step 7. Reconfigure Windows computers to use Azure Information Protection
Reconfigure your Windows computers to use Azure Information Protection using one of the following methods:
DNS redirection. Simplest and preferred method, when supported.
Supported for Windows computers that use Office 2016 or later click-to-run desktop apps, including:
- Microsoft 365 apps
- Office 2019
- Office 2016 click to run desktop apps
Requires you to create a new SRV record and set an NTFS deny permission for users on the AD RMS publishing endpoint.
For more information, see Client reconfiguration by using DNS redirection.
Registry edits. Relevant for all supported environments, including both:
- Windows computers that use Office 2016 or later click-to-run desktop apps, as listed above
- Windows computers that use other apps
Make the required registry changes manually, or edit and deploy downloadable scripts to make the registry changes for you.
For more information, see Client reconfiguration by using registry edits.
If you have a mixture of Office versions that can and cannot use DNS redirection, you can either use a combination of DNS redirection and editing the registry, or edit the registry as a single method for all Windows computers.
Client reconfiguration by using DNS redirection
This method is suitable only for Windows clients that run Microsoft 365 apps and Office 2016 (or later) click-to-run desktop apps.
Create a DNS SRV record using the following format:
_rmsredir._http._tcp.<AD RMS cluster>. <TTL> IN SRV <priority> <weight> <port> <your tenant URL>.
For <AD RMS cluster>, specify the FQDN of your AD RMS cluster. For example, rmscluster.contoso.com.
The <port> number is ignored.
For <your tenant URL>, specify your own Azure Rights Management service URL for your tenant.
If you use the DNS Server role on Windows Server, you can use the following table as an example how to specify the SRV record properties in the DNS Manager console.
Field Value Domain _tcp.rmscluster.contoso.com Service _rmsredir Protocol _http Priority 0 Weight 0 Port number 80 Host offering this service 5c6bb73b-1038-4eec-863d-49bded473437.rms.na.aadrm.com
Set a deny permission on the AD RMS publishing endpoint for users running Microsoft 365 apps or Office 2016 (or later):
a. On one of your AD RMS servers in the cluster, start the Internet Information Services (IIS) Manager console.
b. Navigate to Default Web Site and expand _wmcs.
c. Right-click licensing and select Switch to Content View.
d. In the details pane, right-click license.asmx > Properties > Edit
e. In the Permissions for license.asmx dialog box, either select Users if you want to set redirection for all users, or click Add and then specify a group that contains the users that you want to redirect.
Even if all your users are using a version of Office that supports DNS redirection, you might prefer to initially specify a subset of users for a phased migration.
f. For your selected group, select Deny for the Read & Execute and the Read permission, and then click OK twice.
g. To confirm this configuration is working as expected, try to connect to the licensing.asmx file directly from a browser. You should see the following error message, which triggers the client running Microsoft 365 apps or Office 2019 or Office 2016 to look for the SRV record:
Error message 401.3: You do not have permissions to view this directory or page using the credentials you supplied (access denied due to Access Control Lists).
Client reconfiguration by using registry edits
This method is suitable for all Windows clients and should be used if they do not run Microsoft 365 apps, or Office 2016 (or later). This method uses two migration scripts to reconfigure AD RMS clients:
The client configuration script (Migrate-Client.cmd) configures computer-level settings in the registry, which means that it must run in a security context that can make those changes. This typically means one of the following methods:
Use group policy to run the script as a computer startup script.
Use group policy software installation to assign the script to the computer.
Use a software deployment solution to deploy the script to the computers. For example, use System Center Configuration Manager packages and programs. In the properties of the package and program, under Run mode, specify that the script runs with administrative permissions on the device.
Use a logon script if the user has local administrator privileges.
The user configuration script (Migrate-User.cmd) configures user-level settings and cleans up the client license store. This means that this script must run in the context of the actual user. For example:
Use a logon script.
Use group policy software installation to publish the script for the user to run.
Use a software deployment solution to deploy the script to the users. For example, use System Center Configuration Manager packages and programs. In the properties of the package and program, under Run mode, specify that the script runs with the permissions of the user.
Ask the user to run the script when they are signed in to their computer.
The two scripts include a version number and do not rerun until this version number is changed. This means that you can leave the scripts in place until the migration is complete. However, if you do make changes to the scripts that you want computers and users to rerun on their Windows computers, update the following line in both scripts to a higher value:
The user configuration script is designed to run after the client configuration script, and uses the version number in this check. It stops if the client configuration script with the same version has not run. This check ensures that the two scripts run in the right sequence.
When you cannot migrate all your Windows clients at once, run the following procedures for batches of clients. For each user who has a Windows computer that you want to migrate in your batch, add the user to the AIPMigrated group that you created earlier.
Modifying the scripts for registry edits
Return to the migration scripts, Migrate-Client.cmd and Migrate-User.cmd, which you extracted previously when you downloaded these scripts in the preparation phase.
Follow the instructions in Migrate-Client.cmd to modify the script so that it contains your tenant's Azure Rights Management service URL, and also your server names for your AD RMS cluster extranet licensing URL and intranet licensing URL. Then, increment the script version, which was previously explained. A good practice for tracking script versions is to use today's date in the following format: YYYYMMDD
As before, be careful not to introduce additional spaces before or after your addresses.
In addition, if your AD RMS servers use SSL/TLS server certificates, check whether the licensing URL values include the port number 443 in the string. For example: https://rms.treyresearch.net:443/_wmcs/licensing. You can find this information in the Active Directory Rights Management Services console when you click the cluster name and view the Cluster Details information. If you see the port number 443 included in the URL, include this value when you modify the script. For example, https://rms.treyresearch.net:443.
If you need to retrieve your Azure Rights Management service URL for <YourTenantURL>, refer back to To identify your Azure Rights Management service URL.
Using the instructions at the beginning of this step, configure your script deployment methods to run Migrate-Client.cmd and Migrate-User.cmd on the Windows client computers that are used by the members of the AIPMigrated group.
To continue the migration, go to phase 4 -supporting services configuration.
