Explorer.exe seems to hang after login (getting desperate)

[SR]

I am running XP Pro SP2 with latest updates.

I rebooted this morning and after rebooting, after the login (I have
auto login from tweak UI XP enabled) it just hangs. I can Ctrl+Alt+Del
and open a program but it does not seem to want to load the desktop.

After a while it sems to partially load the desktop but it's very
unresponsive, and when I can get the startmenu to come up it freezes
after I starting going through the Programs tree.

I can get into Safemode just fine. I ran spybot and some virus scanners,
I tried disabling all non essential startup and service items, but this
problem still persists.

What could cause this and how to fix this?

The only thing that changed on my ssytem recently was the addition of an
ATI TV Wonder Pro.

Solved!

If anyone is wondering, this can be caused by a bad "ObjectName" key
value in the registery for the following location:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RpcSs

Make sure "ObjectName" = "LocalSystem"

Hope that helps someone out there
