"Remote Desktop connection has stopped working." problem in Windows 7.

When I try to connect to any of my Windows 2003 Servers from my Windows 7 Ultimate pc I get an error:
"Remote Desktop connection has stopped working". It has something to do with the NLAapi.dll. If I rename this dll, TS works fine. I used the dll from another computer running Windows 7 RC and it also works, but in either one of these two cases, while it fixes the TS connection, it causes other errors, maily with the Network and Sharing center. Long story short, I think there is a bug with nlaapi.dll. I can connect fine to the servers from my Windows XP SP3 boxes. I ran all the updates on my 2k3 box, but still does not work.

Here is the log from the Event Viewer:
