I recently added a new domain controller to my windows2000 & 2003 mixed network. I'm running Exchange 2003 SP2 on a Windows 2003 member server. After transferring all the FSMO's, I dcpromo'd and demoted the previous domain controller to a member server ( I do have more than one GC). The Exchange related services on my Exchange Server keep freezing and I'm forced to reboot the machine. The machine will run for a few hours until the the Exchange services quit on their own and will not allow me to restart. The error message below repeats itself while this takes place.
Category: Service Control
Event ID: 8250
The Win32 API call 'DsGetDCNameW' returned error code (0x54b) The specified domain either does not exist or could not be contacted. The service could not be initialized. Make sure that the operating system was installed propery.
I've attempted to change the domain controller specified in the reciepient update services and was unable to do so. It currently has my old domain controller listed. When I try to browse to the new it's not finding my domain. I have a single domain network.
Any help is greatly appreciated! Thanks! - Dan
