Windows 2000 TS: "error in the licensing protocol" when trying to connect from an XP client

Hi, I have a client who is running a Windows 2000 Terminal Server. They have 10 licenses. Most users can connect successfully. However one user cannot get connected from her laptop. She receives the message "The remote computer disconnected the session because of an error in the licensing protocol" when she clicks connect from her RDP client.

I have tried the fix to delete the MSlicensing registry key. This error is still appearing, same as before. The registry key has not been recreated. Any one have any other ideas? Thanks.

Hi. As I stated, I have already tried deleting the mslicensing registry key. The key is not being recreated after the reboot when they attempt to connect again and they are still receiving the same error message.

Is the user running as 'administrator' on the laptop?

To resolve this problem, right-click the Remote Desktop Connection shortcut, and then click Run as Administrator. By default, the remote desktop connection runs as a user with the lowest user permissions. By default, a restricted user does not have permission to write registry entries to HKEY_LOCAL_MACHINE. Therefore, attempts to rewrite the MSLicensing key fail.

Starting Remote Desktop Connection with administrative credentials provides the permissions that are necessary to write the needed registry keys.

Also what does the user's laptop Event Log show?

Perhaps it cannot find the TS Licensing server.

Hi, the user has gone home for the day. I will connect with them tomorrow and try these options. Thanks.

Okay, this solved the problem. Turned out the user was not an administrator on her own laptop, despite what she though. Once we got her logged in with administrative priviledges, she was able to connect via RDP. Thanks!
