We are currently only using 2003 DCs in one of our environments. After introducing Server 2012R2 machines we noticed that Group Policy for IE was no longer applying.
We found the problem was that IE10 no longer would use the IEM settings in our GPO, and would only use GPP. Of course with no 2k8 DCs, we have no GPP settings.
My question is: What other issues could we face by not having GPPs? Is IE10 the first item to REQUIRE gpp to work properly? We are working on making a case to management and I figured you all would be a great resource!
