Windows 2000 Duplicate SID and event id 12293.

Windows 2000 Duplicate SID and event id 12293.

Shortly after installing SP3 on the BDC and GCS, we started to experience AD corruption.  We restored the System State on both servers for the domain and rebooted.  Since then, once or twice a week a controller may delete a computer or user accound with event id 12293.

Technet had an article stating to prevent this from happening, you are supposed to install SP3 AGAIN, before and after restoring the System State.

Of course, I did not see the artcile until I got the errors.  Typical MS BS.

Now... ntdsa.dll's are on the patch level and running ntdsutil and checking for dups comes out with no errors or dups.  This just happens on occasion.  I am about to try to install SP4 on these 2 servers to fix the problem.  2 questions in 1.

1.  Has anyone experienced this and how did you correct it?

2.  What do I need to look out for updating to SP4 with an Exchange 2k server(GCS also) on w2k and main file server on win2k?  

I read some pretty disturbing things about SP4.

Any input would be appreciated.

I have seen many computers function normally after SP4. I have only seen one that crashed.  As far as E2k+SP4 is concerned - i installed them both and experienced no problems. Bear in mind that it was on a Vmware virtual machine, so don't regard this as a very well researched advice.
