"AD / SYSVOL version mismatch" message is displayed unexpectedly in the Group Policy Results report in Windows
Assume that you run the Group Policy Modeling Wizard from the Group Policy Management Console (GPMC) snap-in on a Windows 8-based, Windows Server 2012-based, Windows 8.1-based, or Windows Server 2012 R2-based computer. In this situation, the following message is displayed unexpectedly in the alerts section of the Group Policy Results report:
AD / SYSVOL version mismatch
- This issue also occurs when you use the Gpresult.exe command-line
tool on a client computer.
- The alerts section of the Group Policy
Results report displays the result of the comparison between the
version of the Group Policy template and the version of the Group
Policy Container (GPC) for each GPO.
This issue occurs because one or more Group Policy Objects (GPOs) cannot be applied because of security filtering or Windows Management Instrumentation (WMI) filtering.
More specifically, a Group Policy is filtered because the Group Policy reporting engine assumes that the GPOs that are related to the Group Policy use version 65535 of the Group Policy template. Therefore, when the assumed version value is compared with the current version value of the GPC that the GPO uses, a mismatch occurs. This mismatch is then reported in the Group Policy Results report.
