Need further help? The official Microsoft documentation for "Add RDS CALs to a license server" is always up-to-date, but the steps above cover the real-world scenarios most admins face.
# Define output file $outputFile = "C:\RDSLicenseReport.txt"
Before we hunt, we must know our prey. In Microsoft RDS, the "key" you need usually comes in two forms:
If you have a valid license agreement but cannot locate the key, your fastest path is always the for VL customers or the Microsoft 365 Admin Center for CSP customers. When all else fails, a 10-minute call to Microsoft Licensing Support with your Agreement number will resolve 99% of cases.
If you see "Product Key" for Windows Server, ignore it. The RDS license is not a product key; it is a License Key Pack ID . Copy the 16-digit code.
