Terminal Server Licensing Error 0xc0110011

This is a known problem with Microsoft terminal server licensing. Apparently this happened due to some corrupted or expired certificates that Microsoft uses for their clearing house. You might get errors about licensing protocol errors when trying to connect or get the 0xc0110011 errors when trying to activate the server again.

Luckily you can fix this problem by deleting the following registry keys (please make a backup beforehand):

  • HKLM\Software\Microsoft\TermServLicensing\Certificates
  • HKLM\System\CurrentControlSet\services\TermservLicensing\Parameters\Certificates.000
  • HKLM\System\CurrentControlSet\services\TermservLicensing\Parameters\Certificates.001

Blacked out login screen

 You may run across a server that is blacked out on the login screen. You can still login but it makes it difficult finding the username or password fields.

To fix this you should look in the registry at:
HKEY_USERS\.DEFAULT\Control Panel\Colors

You will probably notice that all the values or almost all the values have zeros in them. You need to replace these from another server. You can replace these with the values listed below if you don’t mind the colors. Just save the values to a .reg file and import them back in:
