Sysvol not replicating, AD not failing over

I have put in a new Domain Controller (newDC) into our network but are
having problems with the old Domain Controller (oldDC) replicating
sysvol to newDC. The ultimate goal that I'm trying to achieve here is
to be able to shut down oldDC and have newDC take over (eventually
having oldDC only as a backup).

As of right now, the issue lies when I shut down oldDC I start to run
into problems with the active directory (such as not being able to edit
any users info, it just hangs for a few seconds as if it's still trying
to talk to oldDC).

----------------------
Event Viewer Logs:
----------------------
On newDC, I only get two errors (but I think the problem lies in
oldFS's logs, please read oldFS logs before making suggestions).

1) EventID 13566. File Replication Service is scanning the data in the
system volume. Computer "newDC" cannot become a domain controller until
this process is complete. The system volume will then be shared as
SYSVOL.

2) EventID 13508. The File Replication Service is having trouble
enabling replication from "oldFS" to "newFS" for
c:\windows\sysvol\domain using the DNS oldFS.domain. FRS will keep
retrying. (one of the possible causes is listed as "FRS is not running
on oldFS. The DNS settings appear to be okay).

----
oldDC logs:

1) EventID 13552. The File Replication Service is unable to add this
computer to the following replica set:
"DOMAIN SYSTEM VOLUME (SYSVOL SHARE)".
This coule be caused by a number of problems such as: invalid root path
(the root path is correct, i've checked), missing directory, missing
disk volume, file sysem on the volume that does not support NTFS 5.0
(not the case). FRS error status code is FrsErrorMismatchedJournalId
(could be the problem?).

2) EventID 13555. The FRS is in an error state. Files will not
replicate to or from one or all of the replica sets on this computer.

-----------------------
Further Details:
-----------------------
For the active directory settings, if I set the PDC operations master
to newDC, the active directory begins to give problems (like not being
able to map user home dirs for example-- but this makes sense since the
problem lies with sysvol not replicating over).

Microsoft support archives tell me to restore the SYSVOL data from a
domain controller that can replicate files to the domain controller
that cannot (in non-authoritative mode). Problem with this is that
newDC doesn't have an up to date copy of the sysvol since replication
never succeeded.

I'm kind of stumped on this one, been trying to resolve it for a few
days without much luck. Any help would be extremely appreciated!

I would use dcdiag to troubleshoot it. Or this troubleshooting may help too,

Re: Sysvol not replicating, AD not failing over


I just solved my problem, it seems that the problem was with a
correupted SYSVOL replica set.

I followed some steps from "How to rebuild the SYSVOL tree and its
contents": http://support.microsoft.com/kb/315457/

I shut down ntfrs service on both DC's, did an authoritative restore on
the oldDC (D4), a non-authoritative restore on newDC (D2), then started
the ntfrs service back up and all went smooth... was relieved to see
all those red x's dissapear from the event viewer ;)

Going to do a reboot of the DC's later tonight and do a failover test
to see if newDC can maintain the AD without oldDC now that it's
replicating properly. Stay tuned for more troubleshooting if all goes
to hell.
