Remove a replication partner in AD Sites and Services

I have a site, say SITEA, in AD Sites and Services that shows NTDS settings that are set to replicate with 3 different DCs, 2 in SITEB, and 1 in SITEC.  I want to remove one of the replication partners because it is from a site I don't need it to replicate with.

If I right click on the replication partner and choose Delete it says "Are you sure you want to delete this object", which scares me a little because I've never been faced with this situation before.

So, what is the correct way to remove a replication partner so that the DC in SITEA doesn't try to replicate with the DC in SITEC?

Please be 100% right if you answer cause this DC is in China and I don't feel like flying for 14 hours straight to fix whatever happens I still need to be able to get to this DC. :)

to delete the replication for a particular site. go to AD sites and services Inter-site transports -> IP when you click on Ip you should be seeing site links. Goto the properties of the site and remove the relavant site from the replication.
This shouldn't prompt you with any message saying "Are you sure you want to delete this object".

But what you are trying to do is remove replication from 1 particular server. Say if any changes are made on that DC then it wouldn't replicate to your site.

You can delete that without any problem.That wouldn't break any thing.Only would cause AD changes not getting replicated which is not recommended unless you are 100% sure that their won't be any changes made on that DC.
Hey mate,

i had a test system configured which had about 4 sites and replication partners like yours...i deleted replication partners just to see what happened and found that i could simply recreate them if there was an issue

however that was on a local subnet....not 14Hrs away.....

instead of removing the partner, is it an option to assign a ridiculous cost to the link, so that pretty much except in the case of extreme failure, it wont replicate?

Jay_Jay70, that may be an option to extend the cost out like crazy.

Here's more info in case someone wants to revise/clarify their answer:

SITEA has 1 DC in it - DC01

It shows in NTDS settings that it is set to replicate with 2 DC's in SITEB, and 1 DC in SITEC.

However, SITEB is "headquarters" and is the hub, SITEC is simply a spoke.  So SITEA replicating with SITEB should already have the changes from SITEC, since SITEB and SITEC replicate every hour, whereas SITEA and SITEB are set to replicate every 3 hours.  Also, SITEA and SITEC aren't "accessible" to each other, network wise, so I simply get errors stating that it cannot reach SITEC's DC.

So based on that, I can simply go into NTDS settings on that site and delete the DC I don't want to replicate with?  This will NOT affect that DC I delete, correct?  Last thing I want is for it to start having problems simply because I don't want to replicate with it.
If i were you, I would create two Physical Site links under your Intersite Transports, one containing site A-B, one containg Site B-C, in your default IP transport link make sure that you dont have all 3 sites in there....

I would kill to have that trial system here, as i beleive that you can simply delete without issues, but i cannot give you a 1000%....let me grab the cavalry for you, ill see if someone more knowledgeable can post :)


You can remove the link, however (if I remember correctly) KCC will put it back since it will find connectivity.

You *should* remove the link, then create another manual link to SiteC from SiteA and set the cost to a high level so it isn't used unless there is no other link available.  This would be the safest thing to do.  You will likely need to do this from both ends.

KCC will add the link as long as there is connectivity, if you delete the replication partner, then right click on the server in question and select check replication topology it will recreate manually if there is a connection

Magically, after it finally replicated once, it removed itself...weird...but true.

By the way, I did indeed create a new Site Link originally when I created the DC, I wasn't sure why it threw another site's DC into the replication mix, maybe it was a fluke until that DC had replicated and knew what was going on.

Oh well, everything looks correct now for some reason, maybe the KCC knew to remove it as intended?  There is no connectivity between the DC in the site and the DC I didn't want it to sync with so maybe that did it.

Now I need to go back and study up on how ADS&S replication really works....I'm one of those, "But, WHY??" people.

Thanks for all the suggestions and help!
yah, KCC is pretty efficient once there is no link...

Glad is all well though, cheers
