Replication links are maintained under the repsFrom attribute on the NC
head. The attribute contains the InvocationID and replication CNAME for
each partner plus additional replication metadata such as USNs, last
replication success/result, schedule and control data. The attribute value
is constructed by the KCC and is not replicated. Further, it is owned by
the system and, as such, cannot be "easily" modified ("easily" does indeed
mean it can be modified but, in general, it's protected for a good reason).
If you wish to modify it, I would suggest you allow the KCC to do so by
placing the offending DC in a site configured to dissuade other DCs from
using it as a source replica.
Replica links can be adequately dissected using the Windows Server 2003/ADAM
LDP.EXE tool. For example -
1> repsFrom: dwVersion = 1, V1.cb: 275, V1.cConsecutiveFailures: 0
V1.timeLastSuccess: 12723314676 V1.timeLastAttempt: 12723314676
V1.ulResultLastAttempt: 0x0 V1.cbOtherDraOffset: 216 V1.cbOtherDra: 59
V1.ulReplicaFlags: 0x70 V1.rtSchedule: <ldp:skipped>
V1.usnvec.usnHighObjUpdate: 4077980 V1.usnvec.usnHighPropUpdate: 4077980
V1.uuidDsaObj: 1d110953-f6fa-4ed9-986f-c0bf895e52c4 V1.uuidInvocId:

Subject: [ActiveDir] Active Directory Replication - Removing NCs
Hi Everyone,
While continuing with my "evil" tests.... ;-)) I'm trying to figure
something out.
To summarize:
Site links connect sites for replication
Connection objects connect DCs for replication
Replication links connect naming contexts for replication
The first two are stored in the configuration container and it is possible
to view/manipulate these with DSSITE.MSC and ADSIEDIT.MSC.
Does someone know where replication links are stored and how to
view/manipulate these in the directory.
Why this question? For those who remember, a while ago a was testing with
the W2K3 REPADMIN /unhost option to remove a naming context from a GC. The
situation I experience sometimes (for now only on W2K SP3) is that I'm able
to remove a certain naming context from the global catalog without problems.
The event viewer presents me the IDs I expect.
However on the same GC when I try to remove another naming context I receive
the following error:
DsReplicaDel LOCAL_ONLY() failed with status 8450 (0x2102):
The naming context cannot be removed because it is replicated to another
server
(In REPLMON I can see that the GC has replication links for the particular
naming context.)
This results in not being able to remove the naming context from the GC as
expected. At the moment the DC/GC is running W2K SP3 and the command is
executed from a WXP SP1 computer
Does someone know how to continue troubleshooting this, as I cannot
determine how to continue? (I have been looking at my screen for an hour now
and I cannot come up with something... ;-(( )(I hate when this happens!
*^%&*%&*^*&[EMAIL PROTECTED]@ )
Hope you guys can help me!
Regards,
Jorge
