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

1. dcgpofix /ignoreschema and press yes at both prompts.
2. gpupdate

The refresh event viewer.

The problem should be resolved.
