DC Randomly reboots

[Mal]

I have a DC that simply reboots at random intervals.

I have 4 DCs, the problem was first happening on DC1. To
rule out HW problems I swapped the disks out of DC1 and
DC2, but before I did this I moved all the FISMO roles to
DC4.

What happened next was that DC4 started rebooting.

The FISMO roles were all moved back to DC1 & DC2 with the
exception of PDC Emulator, DC4 is still rebooting
suggesting this is linked to the PDC Emulator.

There is nothing in the Event Log that is completely
consistent with the reboots. There are, however, DR
Watson errors 4097 (LSASS.Exe) and MRxSMB 3037 errors
regularly appearing. Microsoft has not released a patch
for the LSASS.Exe problem (only Premier Support) and the
3037 error does not give me any information (After
looking up the status code, it says 'Internal Error
Occurred' - Like, right! Thanks!!).

Has anyone seen this before, is there something very
simple I have missed? Any advice would help!

This may not be the best forum for this question Mal. I believe you'll have
to setup a debugging type option, like a memory dump, to help determine why
this is happening.

To pursue this you should repost this message to the
Microsoft.public.win2000.applications newsgroup or once you have the memory
dump you can upload it for an analysis at the Microsoft Online Crash
Analysis web site:

lsass.exe crash due to negatiate/kerberos/ntlm was fixed in SP4. Check the
fix list.

We are in very similar situation. Our DSs do randomly
reboots and we got the symptoms described in KB324184.
The only problem is that we are running SP4 which should
solve the problem (but it doesn't for us). Please post
the solution if you find one.

Thanks
