Solve GPO replication problems
I have seen this issue multiple time when replicating between Windows 2003 and Windows 2008. Windows 2008 and Windows 2012. If your domain controllers are not the same OS/version this could be an issue.
Here is a quick and simple way to fix your replication nightmares.
Open command prompt on domain controller and run following commands
- dcgpofix /ignoreschema and press yes at both prompts.
The refresh event viewer.
The problem should be resolved.
