To resolve this issue, do the following:- Make a backup copy of the TS Licensing database folder.
- Uninstall (remove) the TS Licensing role service by using Server Manager. Removing TS Licensing will require you to restart the server.
- Reinstall (add) the TS Licensing role service onto the computer by using Server Manager.
To perform these tasks, refer to the following sections.
Make a backup copy of the TS Licensing database folder
Before you remove the TS Licensing role service from the computer, make a backup copy of the folder that contains the TS Licensing database. This is good standard procedure and a backup can be useful if you need to contact Microsoft Customer Service and Support (CSS) to resolve this issue. When backing up a license server, back up both the System State data and the folder in which the TS Licensing database is installed. This ensures that data in both the registry and the TS Licensing database is backed up.
By default, the TS Licensing database is located in the %systemroot%\system32\lserver folder (where %systemroot% is the folder in which the operating system is installed, which is, by default, c:\windows).
To perform this procedure, you must have membership in the local Administrators group, or you must have been delegated the appropriate authority.
To confirm the location of the TS Licensing database:- On the license server, open TS Licensing Manager. To open TS Licensing Manager, click Start, point to Administrative Tools, point to Terminal Services, and then click TS Licensing Manager.
- If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Continue.
- In the left pane, click All Servers, click the name of the license server, and then on the Action menu, click Review Configuration.
- The database location is listed at the top of the Configuration dialog box.

- To close the programs manually and restart the server later, click Cancel.
- To automatically close the programs and restart the server, click Restart now.
