Removing Terminal Server Licenses from an RDP Client

• Microsoft Windows NT Server version 4.0, Terminal Server Edition

SUMMARY

Each Terminal Server Client gets a license the first time it connects to the Terminal Server. The Client connects with that license until the license expires. The license is stored in the Client's registry.

Thirty-two bit RDP clients store their license under the key HKEY_LOCAL_MACHINE\Software\Microsoft\MSLicensing.

WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it. If you are running Windows NT, you should also update your Emergency Repair Disk (ERD).

To clean the Client's license cache, just delete this key (and its subkeys). The next time the client connects to the server, it will get another license.

For 16-bit RDP clients, run regedit /v. Then delete the keys under "\Software\Microsoft\MSLicensing" to clean the Client's license cache. You can also delete the BIN files from \Windows\System\Regdata.
