I have a Windows 7 64-bit machine on a domain network and within seconds of bringing up the desktop, explorer.exe will stop running and never restart. This happens even on a clean boot. If you log on locally instead of through the domain, explorer.exe will stay running until you try to access the all programs menu or search for a program. You can access programs that have desktop icons to click on. I have run Malware bytes and AVG Free and both have returned no results. Any ideas? Thanks for the help.
