During the AD audit at a client’s site, I encountered the following problem:

The gpo tool command does not raise replication issues at GPO levels. However, when preparing a Group Strategy Result report, a warning appears:

AD/SYSVOL version Mismatch.

As a reminder, a GPO replicates through two channels. The GPC (Group Policy container) replicates during AD replication, the GPT (Group Policy Templates) uses FRS or DFSR.

A Microsoft KB exists to solve this problem, the following operating systems are concerned:

• Windows Server 2012 /2012 R2

• Windows 8 / 8.1
