Hello,
We have a Windows Server SBS 2008 DC that we are trying to decommission. It also was our exchange server (2007) but we migrated to O365. We have a new Server 2012 R2 DC up and running. Ive moved the following roles to the 2012 server:
- ADDS, DNS, DHCP
- FSMO roles
- Global Catalog Server
Now when I try to run dcpromo on the SBS server, it gets to the end and fails saying it can't find a global catalog server. Ive check the firewalls and also made sure the NIC is pointing to the new server for DNS. When I try to uninstall Exchange 2007 from the SBS server, I get the same error message stating it can't find a GC server. Does anyone have any suggestions?
Thanks.
