We were a Windows 2003 Forest and all our DC's were Windows 2003 SP2. Some are R2. We are slowly rolling out 2008 R2 DC's and decommissioning our Windows 2003 DC's. Does anyone know of any Group Policy issues with 2008 like older 2003 Policies not working correctly under 2008 R2? I did a lot of checking before starting this upgrade and I did not see anything about Windows 2003. Only Windows 2000 DC.s. Also, isn't there a better way to store Group Policies in 2008? I remember reading something about a Group Policy store and a central location for all polcies. Do you need to be 2008 Native Mode to use this feature?
