I have a remote site named 200_Seattle
There are two DCs in this site.

I have a Datacenter Site with all root Dcs named 500_HQ

There is a sitelink named 200 - 500 SiteLink
In the Sitelink both the 200_Seattle and 500_Hq sites are in the link

We have over 200-300 sites
Each site has its name and the associated subnet

Then that site has a sitelink paired with the Datacenter Site only

Hub and Spoke.

However when I check KCC it looks like it is replicating with spoke Dcs not the Root.


And whaqts even more bizare. Is one of the Remote Dcs has over 200-300 Automatically generated KCC replication partners. Which gives tons of SCOM alerts as there are too many. and the other DC in the Site Keeps given the below KCC error. I am confused as why its replication partners are those in other cities instead of the ROOT _ HQ _ datacenter Site.

How can I control this? or do I need to?

And how do I fix the below error

Domain is mixture of win 2003 and win 2008 servers.






The Knowledge Consistency Checker (KCC) has detected problems with the following directory partition.



Directory partition:
CN=Configuration,DC=domain,DC=com



There is insufficient site connectivity information in Active Directory Sites and Services for the KCC to create a spanning tree replication topology. Or, one or more domain controllers with this directory partition are unable to replicate the directory partition information. This is probably due to inaccessible domain controllers.










User Action

Use Active Directory Sites and Services to perform one of the following actions:

- Publish sufficient site connectivity information so that the KCC can determine a route by which this directory partition can reach this site. This is the preferred option.

- Add a Connection object to a domain controller that contains the directory partition in this site from a domain controller that contains the same directory partition in another site.
