I currently have 4 domain controllers in one site. I am also running Exchange 2010. It is NOT installed on any of the domain controllers.
DC1 - Win 2003 - Global Catalog - DNS server - Holds FSMO roles
DC2 - Win 2003 - DNS server
DC4 - Win 2008 R2 - Global Catalog - DNS server
DC2008 - WIn 2008 R2 - Global Catalog - DNS server
I want to demote DC2 and then decommission it. If there anything in particular I should double check before running DCPromo to demote it?
