Window 2003 Terminal Licensing Server--Corrupted

Bad luck! It happened to me. After running succefully for one and half year of our Win 2003 terminal licensing service, one day it gave me an error message: "The Terminal Server Licensing service terminated with service-specific error 31 (0x1F). General database error occurred, Can't initialize ESE instance - error -501 JET_errLogFileCorrupt, Log file is corrupt."
Don't be panic, although we really need to spend some time on fixing it.
1. Go to services, and check the terminal server licensing service. If it's still showing 'start' mode, then 'stop' it.
2. Rename 'Lserver' folder as 'Lserverold' under C:\WINDOWS\system32.
3.Create a new folder 'Lserver' under the same directory
4. Try to start terminal licensing service. If you have trouble to start it, go to step 7
5. If it starts, it will automatically generate several files under 'Lserver' folder.

6. Next thing you need to do is contact MS clearinghouse to reactive your CALs. The number is 1888-571-2048.

7. If unfortunately, you couldn't start your terminal licensing services, you have to uninstall terminal licensing server and reinstall it. Go to control panel--add/remove programs---windows component-uncheck terminal server licensing. follow all the steps. After it, reinstall it.
