Well wouldn’t you know it, an old issue creeps up in Vista and it has the same resolution as before..
“The remote session was disconnected because the local computer’s client access license could not be upgraded or renewed. Please contact the server administrator.”
1 . Use the Registry Editor to navigate to the HKEY_LOCAL_MACHINE\Software\Microsoft\MSLicensing key on the Windows XP client.
2 . Delete the MSLicensing key.
3 . Close the Registry Editor.
It should now be fixed…
