I have an issue in that new images we have captured starting in August of 2012 do not seem to respond to group policies, even though GPResult shows the policies were applied.
Here are the specifics;
I have a Windows network with two Windows 2008 R2 domain controllers and about 800 Windows XP Sp3 client computers. Since early 2010, we have been using the Microsoft Deployment Toolkit 2010 (MDT2010) to capture images from new base XPSP3 installs on existing hardware and then redeploy them to like hardware. We have been doing this every every new school year since. This school year, we reformatted and installed XP SP3 on our various computer types and captured new images with all of the relevant updates and applications for the new school year. However, none of the newly imaged computers seem to process group policy assignments.
When I run Gpresult form the XP XP3 client, it shows that it is applying the policies, such as drive mapping, browser defaults, etc, but they do actually happen. There are no errors in the System or Application logs of the XP SP3 clients and no errors on the domain controllers.
I can plug an identical hardware computer that is still using the last year image and it does pick up and execute the policies, but the newly imaged, identical hardware XP SP3 computer placed in the same OU does not.
One other thing that has happened between the last school year's imaging and this school year's imaging is that we had a domain controller crash. Initially, we had DC1 and DC2. DC1 crashed over the summer of 2012 and could not be recovered so we installed DC3, joined it to the domain and let it replicate from DC2. I do not see any replication errors in either of the DC's logs. I have spent a log of time chasing this thinking it was related to the DC crash but when I discovered that computes still using the prior year's image were still executing the group policies, I decided that the DC crash could not be the problem.
Has anyone seen this type of behavior? Any ideas?
