Exchange trying to LDAP Bind to a non-existant server

[irbk]

Last week our Schema master and Domain Naming Master, for what ever reason, lost it's computer account. It could no longer communicate with AD. I couldn't run a DCPromo to remove it from AD as a DC, so I couldn't take it cleanly off the domain. I didn't have any choice but to yank it off the network, format C:\ and start from scratch. I managed to seize the roles of Schema Master and Domain Naming Master on a different DC, used ntdsutil to do a metadata cleanup, and built a new box to be the Schema Master, Domain Naming Master, Global Catalog, and CA. I've got all that transferred over cleanly except for 1 thing. I keep getting the following error on our exchange server

   Event Type:	Error

The oldserver that exchange is trying to do an LDAP Bind to no longer exists. How do I get exchange to start looking at a different server?

Thanks in advance.

Check your Site and Services to see what's available to the server.

I'm Certifiable, not cert-ified.
It just means my answers are from experience, not a book.

There are no more PDC's! There are DC's with FSMO roles!

Davetoo - Could you be a bit more specific? I'm not sure what you mean by "Check your Site and Services to see what's available to the server" The Exchange server isn't a DC so it wouldn't show up in AD Sites and Services.

I figured out the error. Found this article

looks like the Recipient Update Service settings needed to be changed. I've changed the settings and expect the error will go away. Thanks for the help!

use ntdsutil to do metadata cleanup and get rid of references to the old GC/DC/
