HI,
"You can re-install a new server with same name (after this one is gone),
or you can rename a NON-DC and promote it (after this one is gone)."
According your comment what i'm looking for is to demote the DC that's
failing from the directory services functions and consecuently delete the
computer account from the domain then promote a new member server to be
domain controller and the set to it the netbios name of the failed DC had it.
ej:
dc1.abc.com = remove from domain and delete from AD
dc2.abc.com=member server new AD but with the netbios name changed
to dc1 once it was remove it from the first one.
Thanks any comments !!
