I am working at a large agency with an equally large number of domain controllers. According to the general consensus of existing staff, the domain controllers are currently running R2 version of Windows 2003 Server. However, when I attempt to install some of the R2 utilities (such as printmanagement.msc) I receive errors that suggest that Windows 2003 R2 is NOT running. When I run WINVER, I see this message: Windows Server 2003, Enterprise Edition, Version 5.2 (Build 3790.srv03_sp2_gdr.080812-1204: Service Pack 2).
On other servers outside this enterprise, I have observed the letters R2 on machines that I know are running R2 in this description. Unfortunately, I need some sort of indication or "Microsoft Approved" method to definitively specify whether or not R2 is actually installed, or if it's installed and the schema is NOT extended yet.
Would appreciate your help.
