I have 2 sites. Site1 with 2 DCs and Site2 with 1 DC.
If I create a new user on Site1 the 2 DCs replicate the user instantly.
The Site2 DC doesn't get the new user replicated to it until some time afterwards. I had a similar issue before, which I solved (on another Domain) by making the servers
Preferred Bridgehead Servers.
Is this the right thing to do? Or is there another way to improve the speed of replication?
