Hello,
I am having an issue where I had a Domain controller die, so I removed it physically, used NTDSutil to clean up the metadata and seize the roles. I removed all references to it in AD users and computers, as well as sites and services. But now when I run ntdsutil it shows me no servers listed for my default-first-name-site. I have 2 showing for that site in AD sites and services. Now everything on the network is really slow, and my mail server, which is on the network, is timing out when people try to send email to it.
I'm lost, please help.
