Active Directory Replication

We brought up a new domain controller on Friday night, which qualifies as the 11th DC in our domain.  When I look in AD Sites and Services this morning, I see that it has an automatically generated NTDS replication with every other dc on the network, while all other existing domain controllers have 2 NTDS replication partners.  Is this typical behavior of a new domain controller which is brought up onto the network, or should I perhaps look into this more thoroughly?
Thanks in advance

This isn't something you should be too concerned about...  Automatically generated is always there by default within each AD Site, but can be manually modified within the NTDS settings of each individual domain controller.  Which is likely the case why the previous DC may only have a few replication partners, the must have been modified manually at some point, or the were moved from one AD site to another at some point?

What I can definitively say is that the other sites have not had the NTDS settings modified, as the majority of the newer domain controllers have been brought up since I was with the company.   I just double-checked and every other site definitely has two partners, which I'm pretty sure is how AD works out of the box.  My working theory is that it's doing this (perhaps) because it's still finishing it's first time replication with all the domain controllers in the forest..  However my confidence level is not high, and that's what prompted me to ask the forum...  Thanks for taking the time to respond.

A way to test whether AD replication is working is to test it.

You might want to consider creating a test OU and some computer accounts and see whether it gets replicated over to the new AD and also create some test folders and files on the SYSVOL and see whether if it gets replicated.

You might want to consider increasing the replication timing so that it replicate faster. :0

Hope the information helps.
