a few problems with Windows 7 that are all over the forums but Microsoft seems to not want to do anything about them.  They all get closed as answered because we should reinstall windows 7 and then not install anything on it or try and use it with our current network setup. I too had the same problem when trying to log back in to my Windows 7 x64-bit pc after using remote desktop through a eee pc 1000 laptop (which has Xandors OS installed.) So once I had ended my session through the eee pc laptop, I would go back to my Windows 7 x64-bit desktop pc and try to log in but it would just hang at the welcome screen with the pointer going in circles. Issue went away once I uninstalled Zone Alarm free edition (using windows built in firewall now). I also uninstalled SuperAnti Spyware free edition just for the heck of it. I have always kept these unchecked to decrease the amount of memory being used during a session. The only thing I like to keep checked, but has been tested unchecked, is the clipboard so I can do fast cut & paste tasks, if needed. Sometimes the net share access can lead this problem, when you disconnected from remote and then opened a share like \\server\d$ to access the sever. BTW you can use psshutdown which is in sysinternal toolset to restart the remote box without reaching it. Im having the same problem. Suddenly
