Users that were previously able to connect to a terminal server are now unable to connect. When you open the TS licensing manager and view the properties of the license server you get the following error:
"The Licensing Wizard encountered an internal error from the license server. Message Number: 0xc0110011"
The license server database is corrupted.
To fix a corrupted license server database, you will need to uninstall and reinstall the TS Licensing service. When you reinstall the Licensing service, you will have an unactivated License server with no TS CALs installed. You will need to call the Microsoft Clearinghouse to reactivate so make sure you have your licensing documentation!
Go into Administrative Tools, Services and stop the Terminal Server Licensing service. Then go to c:\winnt\system32 and look for the Lserver folder. Rename it to LserverOLD.
Now go into add/remove programs, add/remove windows components and uncheck the terminal server licensing option and click next. If the terminal server is install on the same machine make sure you do not change the mode of the terminal server. Then finish the uninstall. Reboot.
After the reboot, go back to add/remove and check the TS licensing box again. Once again, do not change the mode of the TS if installed on this box. Finish the install and reboot.
Check your system event log for two informational event logs: Event ID 5 (TermServLicensing) and Event ID 0 (TermServLicensing). If you see these, proceed to opening the licensing console. You should see your server and that it is unactivated. You will then need to call the Microsoft Clearinghouse to activate the server and to reissue your TS license keypacks. Make sure you have all of your documentation!
