Windows SBS 2003 - Corrupt License Service

If you have a situation where one or more users cannot log on to network resources but otherwise have fine network connectivity then you may have an issue with licensing.

Have a look at the Windows Application Event Log

  • Right click on My Computer and select Manage
  • Select System Tools
  • Event Viewer
  • Application


If you notice errors like the one above stating that "No License was available for user... then go and check the Server Licensing

  • Control Panel
  • Administrative Tools
  • Licensing

Notice that the licenses in the image below are missing and the system has defaulted to five users


The actual licensing file can be found in c:\windows\system32\

It is most likely that this file has become corrupted



Luckily for us, Microsoft has taken a backup for us - You can find it at c:\windows\system32\



To fix the problem stop the License Logging Service

  • Right click on My Computer and select Manage
  • Select Services and Applications
  • Select Services 
  • Locate the License Logging Service and stop it



  • Take a copy of both files you are about to work with
  • Now Rename the to
  • Start the License Logging Service 

If all is well you should now see your licenses back in the Licensing screen.
