Hi - I've been trying to find a fix for a Windows XP Home hangup. I'm finding lots of discussion, but no actual fixes. Can anyone help?

After the welcome screen on boot-up I get a black screen that hangs up the system for a few minutes with a C:\Windows\system32\net.exe DOS box, flashes to full black screen, comes back with the same dos box, then flashes on a C:\Windows\system32\ipconfig.exe box then starts up normally. If I 'x' out the Dos boxes, they just come back.

I've tried some of the standard stuff:

- Updated anti-virus (free AVG) and ran in safe mode.
- Ran CCleaner in safemode.
- Checked start files in system information - nothing looked too strange
- Deleted some old programs (Symantec anti-virus and an old registry cleaner program)
- Installed XP Service pack 3
- Installed and ran spybot search and destroy

I'm running this system on a small home network (wired) set up through XP Home. None of the other systems are having this problem, and none of them show any type of virus (I found one bit of info that says net.exe can be affected by the w32.dabber.c worm but none of my virus programs are finding this worm)

Any suggestions? Thanks, Char

There appears to be something that's trying to start these programs automatically when you start Windows. This is usually either a virus, or the remnants of a virus that hasn't been completely removed.

The files net.exe and ipconfig.exe are normally located in the C:\Windows\System32 folder. You can navigate there, and then submit them to http://virusscan.jotti.org/ to get another opinion about them being infected.

But something is trying to launch these programs - so I'd first suggest a couple of free, online scans to ensure that nothing has gotten by your current protection:

(Be advised that some of these scanners will pickup things in "quarantine" from other anti-virus programs - so review the results carefully)

After that, I'd suggest using this free tool: http://www.microsoft.com/technet/sysintern...s/Autoruns.mspx
To scan your startups for anything that's trying to launch those files at startup (and then disable them).
