We are in the process of migrating from Active directory 2003 to 2008 r2. Step one is to migrate our group policies. We currently still server 2003 as our domain controllers. We use PolicyMaker Suite by DesktopStandards to enhance the group policies to mapped network drives and Printers based on security group membership. Since server 2008 group policies has this capability built in and desktop Standards is no longer developing for Windows Vista and later due to them having been bought by MS, we are migrating to Client Side Extensions. We are pushing the Client Side Extensions to all the Windows XP workstations via startup Scripts and administering the policies from a 2008 r2 server. For about 95% of the user this has not been an issue but for a few users the drives do not get mapped. We have tried to have them log into a different computer and their drives still do not map. However, when other users log into their desktop they get their drives no problem.
Just as an aside, we decided to migrate a few departments at a time so we created a new GPO with the Client Side Extensions and link this GPO to the Dept OU that is being migrated and block inheritance to this OU.
Does anyone have any thought on why only a handful of people are experiencing this?
