به همین سادگی به همین خوشمزگی..

کد:
1. SERVER – Stop the terminal license server in services
2. SERVER – Go to the %systemroot%\windows\system32\lserver\
3. SERVER – Backup both files edb.chk and TLSLic.edb in case method fails (Microsoft holds licence information database in these files)
4. SERVER – Delete both files edb.chk and TLSLic.edb from the directory
5. SERVER – Run registry editor
6. SERVER – Go to the following key
“HKEY_LOCAL_MACHINE\Software\Microsoft\MSLicensing\”
7. SERVER – Note there is subkey named “Parameters”
8. SERVER – Delete subkey (I have noticed that if I don’t delete this key license server returns old database)
9. CLIENT – Go the client that has expired terminal evaluation period
10. CLIENT – Run registry editor
11. CLIENT – Go to the following key
“HKEY_LOCAL_MACHINE\Software\Microsoft\MSLicensing\”
12. CLIENT – Note there are two subkeys named “Store” and “HardwareID”
13. CLIENT – Delete both subkeys
14. DO NOT connect yet to the terminal server with the client!
15. SERVER – Change the date on the server to lets say year 2014 (this is used to change expiration day so you don’t need to repeat following steps every 90 days)
16. SERVER – Start the terminal licensing service
17. CLIENT – Connect the client to the server
18. CLIENT – Note that windows recreated new key in
“HKEY_LOCAL_MACHINE\Software\Microsoft\MSLicensing\”. This new key holds new
expiration date on year what you choose to licence expire.
19. SERVER – Go to the Terminal server licensing in Administrative Tools
20. SERVER – Note that temporary licence now expires on year 2014. Issue date is also at year 2014 but information is not importat for clients to function. Server just saves expiration date on client.
21. SERVER – Return date on server to today date
22. You have Terminal Licence that expires at date that is long in future
