This DC is both a Global Catalog and the Infrastructure Update master. These two roles are incompatible. If another machine exists in the domain, it should be made the Infrastructure Update master. The machine CN=NTDS Settings,CN=Server4,CN=Servers,CN=West,CN=Sites,CN=Configuration,DC=PRODOM,DC=com is a good candidate for this role. If all domain controllers in this domain are Global Catalogs, then there are no Infrastructure Update tasks to complete, and this message may be ignored.
