Urgent:DCs split into 2 groups

Hi all,
We experience replication or pdc role problem.
Those DC split into 2 groups which seems lost the connection.
On PDC, it can replicate and query FSMO with 5 DC.
From another 5 DC, they can't telnet port 53/389, also fail to query FSMO
and replication.

I have setup 1 DC which plan to seize the roles from the PDC.
DNS/WINS are running normal, but DHCP can't assign IP to client computer.
Pls advise how to deal with DHCP and those 5 DC, which connected to the
corrupted PDC.

Many many thx!
Wingo.

Hello Wingo,

Before going on let's see what the source problem is. Was there a restore
of the problem DC or something else? Please run the following commands and
add the output to Windows sky drive as they will be not that small:

dcdiag /v /c /d /e /s:dcname >c:\dcdiag.txt
netdiag /v >c:\netdiag.txt [from each DC]
repadmin /showrepl dc* /verbose /all /intersite >c:\repl.txt (if more then
one DC exists)
dnslint /ad /s "DCipaddress" (http://support.microsoft.com/kb/321045)

Best regards

Hello,
Have you been able to run the troubleshooting commands that Meinolf
requested? If so, please post.

Also are there any firewalls that could be in the way?

Hi Paul/Meinolf,

Sorry to reply late.
From dcdiag/netdiag, most of test are failed.
And fsmocheck warns about DcGetName(PDC_Required) call failed, error 1355.
We dealed with it for days that decided to give up on finding the root
cause.
Setup new DC in 3 problem sites and re-install windows/dcpromo on those
problem domain controllers.

Also, we have to clean up metadata on the new FSMO PDC.
and wait for replicate to all sites.

Here are some ref searched from internet which 90% the same as my case.

Hello Wingo,

When the replication is done run the commands again and add them to the posting.
