DCPromo and vCenter - Demoting Server 2K3 drops hosts from vCenter
I recently promoted a new 2K8 R2 server to be a domain controller. All of the roles were transfered to the new server, and I demoted the server 2k3 DC. After that, vCenter started to lose the hosts connection. One hosts was disconnected from vCenter right away and the other 4 followed. Luckily I took a snapshot of the 2k3 server and reverted it. After that was completed, I was able to reconnect the hosts. What would I be missing that would cause this issue. Thanks in advance for your assistance.
Can you pls check that the DNS entires for the esx hosts are there in the new w2k8 DC?
You reverted a Domain Controller, from not being a DC to a DC, how is your Active Directory?
check communication between vCenter and the hosts, can you ping by hostname, and IP addresses, and also tracert by IP address?

I did check, and the ESX hosts have a DNS entry for the 2k3 server and our 2k8 DNS server. I just now changed the DNS server from the 2k3 to the new 2k8 R2 server. I will try the demotion again tonight. Thanks for the responses.
