When trying to log onto a computer with Windows XP Pro SP2 (either onto the domain or in Safe Mode), get a DEP (Data Exception Protection window indicating that it has closed Microsoft DirectPlay Helper. If I close the error, it keeps coming back and never displays the desktop. It appears it does this when trying to start Explorer to show the desktop.
I can do CTRL+ALT+ESC and bring up the Task Manager. I can also start in Safe Mode, Command Prompt. I've tried doing this and trying to run sfc /scannow but it can't find sfc. I've also tried starting from a Windows CD and going into Repair and running sfc but again, it says it can't find it.
Can anyone tell me how to fix this without reinstalling Windows? Thanks!
