AD error setting up DFS replication

[Kathy de la Cruz]

Hello,
I am trying to recreate a DFS replication group with 3 members (hub &
spoke). 2 members seem to be fine, but one is causing a problem.
In the replication group setup, in the Add member step, I get the error

CCYV-WIKI: The DFS Replication subscriber object cannot be created in Active
Directory: A value in the request is invalid.

When I'm adding this member, it can find the server & the folders to be
replicated, without problem. I am logged in as a domain admin on the "hub"
computer. The other 2 members are in different domains (all part of the same
forest), but the user I'm logged into has domain admin rights on the other
domains.

Does anyone know where I can start looking to find out what this error is?

It might be worth noting, that I am recreating this replication group,
because about 10 days ago, this member stopped replicating -- and there was
an AD error every hour in the event viewer (The DFS Replication service
detected inconsistent msDFSR-Subscriber object while polling for
configuration information. The object at
CN=1b309c2d-6702-4a54-9c08-bf40b5f3c228,CN=DFSR-LocalSettings,CN=CCY-WIKI1,OU=Server,OU=CY-Server,DC=CCY,DC=CC,DC=CORP
references another object at
CN=1b309c2d-6702-4a54-9c08-bf40b5f3c228,CN=Topology,CN=ReplicateWiki,CN=DFSR-GlobalSettings,CN=System,DC=CCI,DC=CC,DC=CORP that does not exist. ).

I have completely deleted (I think) that replication group -- and cannot
find any trace of it in the registries or in AD on any of the computers.
However, I cannot add this computer to the new replication group.

Any advice would be greatly appreciated!

One note: I mentioned that the 2 other members seemed to be working fine
(well, they were working fine under the original replication group which I
deleted) ... but now I am getting a similar AD error in the event log - they
are not replicating either:

The DFS Replication service detected inconsistent msDFSR-Member object while

polling for configuration information. The object at

CN=dbf2327c-21f3-4b3a-a837-24e570d47738,CN=Topology,CN=Wikiplicate,CN=DFSR-GlobalSettings,CN=System,DC=CCI,DC=CC,DC=CORP
references another object at CN=CCSV-WIKI,OU=Domain Server,OU=CS -
Server,DC=CCS,DC=CC,DC=CORP that does not exist.

I don't know where to look to find the problem -- I've looked in AD users &
computers, and I can see the items in question, and have looked all thru the
properties & security tabs & can't see anything wrong.

Thanks

Hi Kathy,

While checking that previous entries are completely deleted, did you check
and confirmed that all the entries are deleted from Adsiedit.msc as well?

Are you using the same DFS member names that were being used previously?

If yes, is it possible for you to use different names and try again?

Hi Vipin,
Thank you for your response -- I was indeed using different names.
But it turned out hte problem was a trust issue between 2 of the domains,
which our network admins fixed -- and after that I was able to recreate teh
DFS configuration with no problems

Thanks,
Kathy
