We've got a couple of DCs in our LAN. Besides we have a temp dc for testing
purpose. The system was down for about four months and I want to bring it
back online. How to?

Esp. how do I avoid the replication with the AD? I do not want the working
DCs to get the outdated informations of the temp dc.

Thanks!

Maik.

Don't even bother bringing it up as a DC.

Do a DCPromo /forceremoval (SP3+), clean up
AD on the other DCs with NTDSUtil "metadata
cleanup", and then DCPromo it back a a (new)
DC.

They will not -- they will refuse do to the lifetime
expiration but don't even bother. Just do the DCPromo
"cycle" -> non-DC and (optionally) back to ->DC.

NTDS metadata cleanup

Search Google for:

[ NTDS "metadata cleanup" remove DC Domain ]

[No need to add either site:microsoft.com OR microsoft:
since the NTDS and other terms make it Microsoft specific
by itself.]

Unless you WISH to restrict answers to the site:microsoft.com
for some reason.

[ NTDS "metadata cleanup" remove DC Domain site:microsoft.com ]

Key points to NOTE when doing the metadata cleanup:

You CONNECT to a WORKING DC.
You SELECT the missing/dead DC or DOMAIN
