Well that went easy. DC1 is completely out of the picture now, the domain is
running on DC2. I have one more follow up question.
I plan on reinstalling DC1 as a domain controller, but I don't want to rely
on it for anything until I am certain that the random lockups are cured -
even if it means replacing all hardware. So for now DC2 is it.
However, I shouldn't have a dc share the Infrastructure master role and the
global catalog. Is it alright to share these roles if there is only one dc
on the domain? Once I bring DC1 is it better to move the GC to it or keep
the GC on DC2 and just move the Infrastructure Master role to it?

you could also do a FORCE DEMOTION offline and promote after the cleanup of
the metadata and replication of the cleanup
you cn of course try a normal demotion but I suspect that will not
succeed...

Thanks for the help, I think I'm begining to get my head around this one.
Jorge, when you say disconnect the promoted DC, I assume you mean the new
DC1 I threw in the mix. Can I just pull the ethernet cable, clean and
reconnect - that doesn't seem right; I would rather not wipe and reinstall
windows... I'm thinking I should demote it with dcpromo, then delete it
from
AD, then when AD is clean and running on DC2 rejoin the domain and
repromote
it to be the new DC1. Does that sound reasonable?

you did not clean the AD metadata of the DC that died as you should!
just deleting the computer account is not enough
see: http://blogs.dirteam.com/blogs/jorge/archive/2005/12/03/213.aspx
in your case I would:
* disconnect the promoted DC
* clean the AD metadata as needed
* seize FSMO roles as needed to another live DC
* install and promote a new DC (make a GC as needed)
* relocate the FSMO roles as needed

I have two DCs in a Win 2003 AD network, DC1 and DC2. DC1 crashed. I
removed it from Active Directory by right clicking on it in dsa.msc and
choosing delete. Then I rebuilt it, naming it DC1 again joined it to
the
domain and ran dcpromo. Everything works, although its only been a
couple
of
days so give it time.
I started thinking about it, and am wondering who my FMSOs are.
Checked
system log on DC1 and sure enough got an error 16651 "The directory
service
is missing mandatory configuration information, and is unable to
determine
the ownership of floating single-master operation roles". Also getting
some
warnings in the Directory Services logs in both servers, NTDS 1232
replication errors all relating to an inability to find the server with
these
roles.
It looks like there are risks if you introduce into a domain two
servers
with these roles, so I would like to keep them on DC1 "just in case"
even
though it has been wiped and reinstalled. This server is still
randomly
locking up on me, more than likely a hardware problem, so I have to
consider
the possibility that it will be out of commission at some point.
Should I just go in and seize the roles onto the new unimproved DC1?
Any advice/comments/sympathetic laughter would be greatly appreciated!
