Removing a Domain Controller from Exchange 2007

Hi,

Our exchange server is defaulting to a non-existent domain controller when querying with powershell. I looked in Server config --> System settings and it is set first in the 'Domain Controllers being used by Exchange' section whereas the global catalog server is correct so not affecting users.

Anyone know how i can get rid of the non-existent DC. I was under the impression that Exchange would just drop it if it wasn't available

Thanks
Neil

Thanks guys for the help.

In the end, I realised that the domain controller was in our backup datacentre so is valid.

Is the dc still listed in active directory?  Was the dc removed or is it just offline?

If it has been removed, and dcpromo didn't remove the records properly, remove the records from active directory, and then yes, Exchange 2007 should find the new dc.  Here's an article from exchange forums regarding dc selection in exchange 07

To get rid of non-existing DC you have clean up the instences of the non-existing DC from AD using metadata.
