Active Directory Sites and Services, issue with replication

Posted on 2014-08-12

Hello all,

This is a bit weird to me, but I am not sure what is wrong.  Background Info.

Windows 2012R2 servers running in Forest/domain functional level 2008r2.
Two Sites, connected with a 30MB vpn connections
Site A is main default site, Site B is remote site.
Site A contains a server with all FSMO roles.
Site B contains a server with R/W AD controller
In Sites and services, everything is default.  No custom links.
Intersite Transport is the "DEFAULTIPSITELINK"
Active Directory appears to be healthy.

I have two sites in Sites and services.  Each site has 1 server.  Each site has more than one subnet attached to it.  All the site links are automatically generate.  repadmin /kcc shows no errors, repadmin /syncall shows no errors.

When I create a user on a server in Site A, the user doesn't show up as a user on the AD server in Site B.  The converse is also true.  It is the same for new computers that join the domain.  I have waited 24 hours to see if the users would replicate eventually, thinking it was a timing issue.  Nope, not even after 24 hours.

If I move AD server in Site B to site A, the users that were created when the server was in Site B do not replicated to the server in Site A.  BUT......With the servers in the same site, if I create a brand new user, the user is IMMEDIATELY replicated to all servers, and all is good.  

After creating the user, and seeing that is replicated to all the servers, I can then move AD server from Site A back to Site B,  change password, change username, change anything, and it is replicated to all the servers.

I can freely move FSMO rolls between servers that are in different sites, so I feel confident that replication is working properly.  Since the domain was built with 2008r2, it is DFS replications, and all looks good in the console

Is there anything I can check to see what is going on.  Any, "A HA!" moments that anyone can share?

    If you create a user in one site and then force replication from that site to the other (without moving a DC), does the user show up at the other site?

    Hello DrDave,

    I just did that, and the user SHOWED UP! me thinking.

    I looked that the IP DEFAULTIPSITELINK, and then noticed that it was set to 1800.....30 hours.  So when I came back about 24 hours later, I was still 6 hours short.  I changed it to 90 minutes....

    But wait, there is more.

    For the fun of it I went into the replication schedule.  Yep......the entire schedule was set to "Not Available" except a very small 60 minute window on saturday.  Fun.......
