Check to make sure DNS and replication are working properly on ALL domain controllers. Nearly everything that goes wrong with AD has to do with DNS being messed up. You can us ForceDCRefresh.cmd my ForceDCRefresh.cmd script. Make sure you view the contents and understand what it is doing before using it. Run this on all DCs if you are comfortable with it. It will help you flush out errors in replication and possibly fix some DNS and replication issues.

If the gpupdate doesn't work cleanly at the end, you know you have issues.
You can also use
repadmin /replsum /bysrc /bydest /sort:delta >replsum.txt
as an AD replication healthcheck.
It might be a good idea to check the bridgehead configuration as well. Use the command:
repadmin /bridgeheads

KCC can bomb due to replication problems. You may think replication is working fine, but a problem might actually exist. You need to know who the bridgeheads are and verify the replication topology. I have sometimes found issues here that have fixed replication.

You would run the command that I gave you above in a command prompt.
repadmin /bridgeheads
Beyond that, you have to have the skill to look at the configuration inside of AD sites and services and combine that with the network topology of the WAN/LAN and decide if the bridgehead configuration is appropriate for that configuration.
