I've inherited a Windows 2003 active directory single domain spread across multiple site locations. I'm checking configuration because previous admin left without leaving any information about his design choices. Actually we have:
HEADQUARTER: (circa 300 users) SRVHEAD1 - holding all FSMO roles (virtual host on vmware infrastructure) SRVHEAD2 - Global Catalog (physical host in a separate room)
BRANCH1: (circa 30 users) SRVBR1 - GC
BRANCH2: (circa 20 users) SRVBR2 - GC
BRANCH3: (circa 10 users) SRVBR3 - no GC configured.
Each branch is connected to headquarter via a MPLS circuit. Connectivity is not always 100% reliable. Headquarter and branch sites have a relative site in Active Directory Sites and Services.
What is not clear to me is why only one GC on headquarter... what if I enable GC on BRANCH3 and on SRVHEAD2 ? There may be problems? And with only one GC on headquarters, in case of troubles with the GC holdin server can I rebuild it replicating from another server? Thank you !
