The computer is down and there is no way to login?  What DC had the FMSO roles?

ok so the server can't even be turned on

Step 1:  Metadata cleanup (do this from a good DC)

Did that server hold any FSMO roles.  If it did seize those roles

...and a Microsoft KB with the official KB articles

If that was the FSMO role holder then you need to seize roles to another dc other wise you are good to go with metadata cleanup

Seize role: http://www.petri.co.il/seizing_fsmo_roles.htm

One more question. Instead of doing metadata cleanup with NTDSUTIL could we do it manually like in ADSIEDIT for exemple?

Not sure but there is really no reason to not use NTDSUTIL.  In windows 2008 and higher the metadata cleanup is even easier.  In those versions if you delete the DC using ADUC then the metadata cleanup happens automatically.


Thanks

Should I force Active Directory replication by using "Repadmin.exe" at the end?
