cal issues with clients system restore?

Marketing_Insists used Ask the Experts™
Occasionally, a client gets the error:

    The remote computer disconnected the session because of an error in licensing protocol.

I still have hundreds of licenses in the pool, so not really sure what the deal is, could it be system restore on the client?  I don't have the problem on thin clients, just the occasional vista machine or home edition of something, generally a users personal system.

I also use deep freeze on the terminal servers - I don't believe that would cause a issue, obviously no DeepFreeze on the licensing server.

Well here’s the solution to fix this problem:

This actually is a registry fix. You’ll be prompted to delete a few keys and subkeys and hence it’s better if you take a back up of your registry manually, so that you can restore it if something goes wrong during the process.

If you do not know how to take back up of your registry manually follow this tutorial : Tutorial to to back up the registry in Windows Vista or in Windows XP.

Once you have taken the back up,

1> Click on Start Menu –> Go to Run Command box –> Type regedit –> This opens the registry Editor.

2> Navigate to HKEY_LOCAL_MACHINE\Software\Microsoft\MSLicensing

3> Delete all the keys under MSLicensing : both HardwareID and Store keys and their subkeys. If you are not sure how to delete the key and its subkeys, just rename them as follows : HardwareID to HardwareID-temp and Store to Store-temp.

4> Reboot the system. Rebooting will create new Keys under HardwareID and Store and this will fix your problems.

5> If you had renamed the keys and subkeys instead of deleting them, navigate to HKEY_LOCAL_MACHINE\Software\Microsoft\MSLicensing and you’ll the two newly created folders – HardwareID and Store. Delete the old HardwareID-temp and Store-temp and close the registry editor.

That’s it !..."
