Problem

At a client this week, they were having a LOT of mail flow problems. Looking at the queue viewer, I could see that all their mail was sat in queues waiting to go into their mails stores. There was a queue for each mail store, and the error on each was "451 4.4.0 DNS query failed Exchange Server error in message queue". Looking in the Application log it was full of Event ID 205, and 16025 Errors Stating;

Event ID 205

No DNS servers could be retrieved from network adapter {GUID} Check that the computer is connected to a network and that the Get-NetworkConnectionInfo cmdlet returns results.

OR

No DNS servers could be retrieved from network adapter {GUID}. Verify that the computer is connected to a network and that the Get-NetworkConnectionInfo cmdlet returns results.

 

Solution

First you need to get the 'Identity" of your actual network card with a Get-NetworkConnectionInfo command, (make sure the correct DNS settings are set for this NIC, i.e. it's not pointing to a PUBLIC DNS server!)  Once you have it, change the Transport service to use this new ID, with a Set-TransportServer command.

Set-TransportServer {Name-Of-Server} -InternalDMSAdapterGUID {GUID} -ExternalDNSAdapterGUID {GUID}

Set Transport Server GUID

Then Restart the Microsoft Exchange Transport Service and the Microsoft Exchange Mailbox Transport Service.
