Fix The Remote Computer Disconnected the session because of an error in the Licensing protocol in Windows Vista. If you have this problem in Windows XP Pro / Windows XP, read this post : Fix MSLicensing Protocol Error in Windows XP.
The procedure to fix this issue is almost similar to the one described for fixing it on Windows XP, except for one extra step. Here’s the step-by-step process :
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.
5> After rebooting (ensure you are logged in as administrator), click on ‘Start‘ menu–> ‘Programs / All programs‘ –> Accessories
6> Right Click on Remote Desktop Connection and select the option “Run as Administrator“. This will recreate new Keys Hardware ID and Store under MSLicensing.
7> If you had renamed the keys and subkeys instead of deleting them, navigate to HKEY_LOCAL_MACHINE\Software\Microsoft\MSLicensing and you’ll notice the two newly folders created – HardwareID and Store. Delete the old HardwareID-temp and Store-temp and close the registry editor.
This solves the problem and you will be able to connect to remote servers using Remote Desktop Connection.
