Windows 2003 SBS sp1 domain with Secondary DC loses Global Catalog when SBS is shut off or DNS is off on PDC
Posted on 2007-09-27
I had a Windows SBS 2003 sp1 server running our domain. I added a Windows 2003 R2 x64 EE server as a DC, and Global Catalog, with Exchange 2007. I have configured DNS on the second DC, and configured as AD Integrated. My goal is to DCPROMO SBS, and remove it from the domain.
I am experiencing issues when I shut DNS off on SBS DC, or power off the SBS DC. Exchange and other services cannot find a Global Catalog server. I could use some help figuring out why GC becomes unreachable, and also getting SBS properly DCPROMO out of the domain.
Thanks in Advance for any help.
