I am going to be running the Windows Server 2003 r2 upgrade onto all my servers. Right now they are all running Windows Server 2003 sp1. I have two domain controllers, file and print, email, etc, etc.
I want to know if I need to run the adprep /domainprep while upgrading my servers? Specifically do I have to run the adprep on my domain controllers?
I am not an Enterprise admin. My domain is a child domain...the parent domain controller is located at a corporate office far away. Therefore I don't think I even have rights to run an adprep. Furthermore the only functionality I really want from the R2 upgrades is the Printer Manager, updated Shadow copies features, updated disk quota features. I am not really interested in the features that pertain to Active Directory and domains.
Also if there anything else I need to be aware of when upgrading my servers to R2? Any hiccups I should expect?
