I've just inherited (isn't it always the way!) a Windows Domain. The domain is spread across 2 sites.
Site01 has 3 DCs & Site02 has 2 DCs.
If I create a user in either site, the other DCs in that site, immediately replicate and show the new user. The new user is not shown in the other site though.
If I manually run the following command, everything syncs and the new user appears:
repadmin /syncall issdc01 /APed
In the Inter-Site Transports DEFAULTIPSITELINK the replicate every time value is set to 180 minutes. I thought this was the solution, but on another Windows Domain, this is the same, but replication takes place across sites immediately.
What can I check to resolve this issue? We are running Windows Server 2008
Results of dcdiag /test:dns show a server that is no longer part of our domain:
TEST: Delegations (Del)
Error: DNS server: oldserver.win.domain.com
IP: [Missing glue A record]

We have set the DEFAULTIPSITELINK to 15 minutes for the replication time.
Local DCs replicate instantly... across different sites, it depends on this replication time.
Change this to 15minutes, create a new users, it will replicate instantly across local DCs, wait 15 minutes, it will replicate across different sites.
