I have an issue where exchange fails to send mail. The queue fills up and when I check resolution for the remote host via nslookup (to my local DC) I get no IP address. If I restart the DNS service suddenly I am able to resolve the remote host. Any ideas on a correction for this other than restarting my dns server service every hour?
 
Would you please post and error from your App, System, DNS, Security logs on the DC and Exchange servers.

Event ID : " " and description most helpful.
 
I get no errors on my DNS server. I do get this on my Exchange server:

Event Type: Warning
Event Source: MSExchangeTransport
Event Category: Connection Manager
Event ID: 4000
Date: 5/25/2007
Time: 9:18:52 AM
User: N/A
Computer: xxxxxxx
Description:
Message delivery to the remote domain 'anl.com.au' failed for the following reason: Unable to bind to the destination server in DNS.
 
I'm seeing a lot of articles on Google relating to your issue. Do a google search on - event id: 4000 unable to bind dns
Seems to be different issue depending on which version of OS and Exchange you are running.
