Hiya,
We have a single network, spread across 2 sites via a 30Mbps leased line. Each site has 3 DCs in it. We are noticing some oddities in the 2nd site in that AD/Group Policy doesn't seem to be working properly.
For example, we added an MSI to our Software Installation GPO that worked absolutely fine in one site, but no computers at all are picking up this change in the 2nd site. The GPO is at the OU level rather than site based. The source of the MSI is on a DFS-R share that is available in both sites.
A few months ago we had similar issues with preferences - we added some printers and again no computers in the 2nd site were picking them, until we replaced the last physical 2008 R1 DC with a new 2008 R2 install, so we hoped the issues were gone, but clearly not.
Is there anything I can do to make sure all DCs are in sync with each other?
Thanks
