We currently run Exchange 2003 SP2 on a W2003 member server. We wanted to introduce a new DC (2003)onsite to replace existing DC (2003). We installed the server, ran dcpromo, mvoed the DNS from the old DC to the new DC.
We then moved the FSMO roles for the old DC to the new DC. Both DCs are GCs.
We then updated the Recipient Update Service on the exchange box. When we took the existing DC offline exchange stopped working. DSAccess on the exchange box is set yo autodiscover but discovered nothing when the old DC was disconnected. We manually set DSaccess to look to the new DC but it did not wok.
Has anyone got any ideas? Have we missed something?
