Active Directory not working after restore

[chai]

Hi there,

Recently my dc, which hold all the master roles hard disk
crash. I replace the hard disk and perform restore from
last month (bit old) in active sirectory restore mode.
Which I hope the server that holding the master role can
online back and replicate the lastest data from other DC
(I got 3 DC).

However, after restore. The OS is working but the Active
Directory is not. When I try do manual replicate using AD
sites and services, error message "the target principal is
not correct". After a while, the sysvol and netlogin share
disappear. Now whenever I try to opern the Ad users and
computers, it point to the another DC.

How or what should I do?

If come to worst case, how can transfer the master role to
another dc? the problems now is when I do this from
another DC, error message say the FSMO cannot be contact!

Help and thanks.

Chai

Hi

With regard to the last point, you need to seize the FSMO roles.

Using Ntdsutil.exe to seize or transfer FSMO roles to a domain controller

If the original server was just a DC, you could recover by seizing the roles
to a working server and rebuilding the original from scratch.

Make sure you don't seize the roles and then restore the original from
backup, as more than one server will believe it has FSMO roles.

Hope this helps

Oli

In addition to the previous post you may need to reset the secure channel of
the DC to resolve the "target principal name" error. This article shows you
how to reset the channel
