My system has been running fine for months then in the last several days I set up access to my computer through Remote Desktop. I have a password to logoff my computer. Since I have set up Remote Desktop 2 days ago even when I am home in front of my computer whenever the screensaver starts it takes me back to the "Welcome" screen and requires that I enter my password to get back to my desktop.

I dont actually know if remote desktop sarted this problem but the only other new thing that I did on my pc in the last 2 days other than set up remote desktop was do a windows update and download Microsoft .Net framework version 1.1.
