Hi,

I need to rebuild one of ours W2K domain controllers,
and wanna make sure the steps I will be doing are right.

First Question:
Do I need to decommission it first (dcpromo it) ?
or should I just go ahead, reformat the drive and rebuild
it and run dcpromo after that?

Second Question:
Everything would be restored to the original configs, like computer name. Would I have a computer name conflict ? because its own name already exists on the other DCs?

Third Question:
is there any steps I need to be aware of from your experiences?

I would appreciate any helps you can provide
John

In general dcpromo, remove it from AD & DNS, rebuild it. Does this server have a special role other than being a DC?

Primarily its just a DC, but it has other apps like Veritas for backups.

Just be aware even though it will have the same name it will have a new SID and GUID.  I don't know off the top of my head whether Veritas tracks this or not, AD certainly does.

so should I just go ahead rebuild it without dcpromo-ing?.
if AD tracks it, would I have a name conflict later on?

No, I would dcpromo first, then while it's down remove it from AD and DNS.

That happens when you refresh the page.  Use the reload page option at upper left hand of the screen.  It's something to do with how they coded the site.  Glad I could help.

MSGEEK, forget to tell you this, there is a chance that I dont need to rebuild the machine if I can fix the Raid Parity but there is a change it might blow up.

Here is the thing, If I have not decommisioned it, then the server blows up. what should I do beside removing it from AD and DNS while its down, any other steps I need to do?

As long as your clients aren't mapping to it you shouldn't have an issue.  AD DCs replicate all information, if they are in native mode and one goes down you will recieve AD replication errors, but the system will still run.  You may loose some sped as they do share responsibilities and it will take a few minutes for the remaining server to pick those up.  That's why I recommended the dcpromo, it does this manually rather than relying on the OS to pick up something unexpected.
