To reset the trial license for Terminal Server Microsoft Windows Server (2000 and 2003) as follows:
- Disconnect all of the client terminal
- On the server shut down the Terminal Server Licensing
- Move the contents of the folder% WINDIR% \ system32 \ LServer in a temporary folder (used only as a backup)
- The folder will be empty LServer
- Restart the Terminal Server Licensing service
- For each client to clear the registry key HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ MSLicensing
To reconnect to the server to each new client will be granted a new temporary license for 90 days (120 for Windows Server 2008). Warning: The procedure described is not a CRACK but a procedure described by Microsoft itself, to use a case of licensing issues such as corruption of the database.
UPDATE: I'm doing some testing on Windows Server 2008
Technical Information
LServer folder contains the following files:
- Edb.log - Register of transactions on the database of licenses
- edb.chk - Control file used to report the use of the database during the transitions
- Res1.log - Wires registry backup, in case you run out of disk space. Limited to 5MB
- Res2.log - Same order of the previous file
- TLSLic.edb - The current license database
- temp.edb - Used to store information about transactions in progress

Possible problems:
- Error code 31 to restart the service: you create a new folder instead of draining the existing one, check the folder permission lserver

Hello, Thanks for the article but I was wondering you have completed the tests for Server2008? If you are successful with that? Were you able to reset the trial period?
Thanks and Hello

Hello Alexander,
the server is in production before I could conclude the evidence and lack of time and I have not completed the necessary checks, sorry.

I had a similar problem with a client that was connected in RDP to Windows Server 2008.
Solved by simply deleting the registry key HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ MSLicensing from the client machine.
The first time you connect to the server, generates a new ClientHWID with a new ClientLicense, the key is compared with a copy on the server. Of course, not finding a match, it will run a new temporary license for the next 90 days. Try it!!

Hello guys, I wanted to know exactly what to delete from REGEDIT, let me explain better I have to delete the folder directly from MSLicensing HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ MSLicensing or content? always the last thing on MSLicensing folder, the guidance described above, the last "dot" for each client to clear the registry key HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ MSLicensing, that is exactly what should I do? each pc in my house connects to the server using Remote Desktop user name and password, but every client I can not change the registry because of the restrictions (Users). I can edit the registry only from your administrator. thanks
