I've been having a bizarre problem for the last few days and can't seem to figure it out. I'm running XP Pro SP 2. After about an hour, my network connection will stop working.
At the same time, as I try to troubleshoot, applications will "fail to initialize". The applications often include IPCONFIG and Task Manager (which generates error code "0xc0000017"). I have no clue what would cause a network connection to drop AND task manager to fail to initialize.
Running my email program in the background to provide a continuity signal (yes I know - an old school fix - and it didn't work)
Repairing winsock (netsh winsock reset)
Repairing the network connection ("Windows cannot finish repairing the problem because the following action cannot be completed: Failed to query TCP/IP settings of the connection") Google has not been my friend in figuring that one out...
Confirming that various network related services are started (or set to automatic)
Turning off my firewall.
Flushing the DNS Cache
Moving the network card to another PCI slot
Using a different network card
Running Virus / Trojan scans (although my gut feeling is that this is a network and/or system issue and not malware issue)
and probably a few other fixes which have slipped my mind.
This is going to take a reply from someone that really knows his/her stuff when it comes to networking/system issues. I'll look forward to your replies. Come, pull your hair out with me.
