Help- w2k server has been rebooting


I'm having some trouble.  I have a w2k sp4 server that has started rebooting itself whenever I go into it.  If I leave it alone, it's fine.  

I uploaded the two memory dump files:

The event log gives:

The computer has rebooted from a bugcheck.  The bugcheck was: 0x00000051 (0x0000000c, 0xc0000005, 0xbdfadb74, 0xbdfad7cc). Microsoft Windows 2000 [v15.2195]. A dump was saved in: C:\WINNT\Minidump\Mini032807-02.dmp.

Does it do the same thing if you remote desktop into it?

I don't think so.  I was in PC anywhere and TS all day long.

You have a registry problem.  The minidump bugcheck info is:
kd> .bugcheck
Bugcheck code 00000051
Arguments 0000000c c0000005 bd5c5b74 bd5c57cc

How would you trouble shoot that?  Restore from backup?  

I logged in under a different user, and played around for 15 minutes -- no crashes.  

Is there anyway to tell where the registry corruption occured?
Rick HobbsRETIREDCommented:
If you can get in as another administraotr equivalent user, it could actually be a Profile error eventhough the bugcheck gives 0x51.  Restore the bad profile from backup and see if that resolves the problem.  If not, restore the last backup you have of the System State.
jmerullaAuthor Commented:
ok- let's see if this solves the problem, if not, I'll do the restore.  

do you mind if I leave the question open?
Rick HobbsRETIREDCommented:
You decide when to open or close a question.  It is always a good idea to wait until you have tested a solution befroe closing.
