hi,
 
seems that the primary dns fails ... maybe some zone-loading problems or syntax error.
you could check the logfiles on that server for loading errors.
does the first dns resolve anything else ?

Hi all,
 
We are having an issue sending a message because of DNS and I am kind of baffled as to why. A message in the queue is destined for the domain dis.dk but I am getting the following message in the queue
 
Failed to deliver to 'amo@dis.dk'
SMTP module(domain dis.dk) reports:
dis.dk: DNS server failure
 
The /etc/resov.conf on the CGPro server looks like this
 
nameserver 155.47.64.174
nameserver 155.47.105.40
 
 
The 2 DNS servers are our Windows domain controllers. If I query dis.dk against the first I get nothing, if I query dis.dk against the second it does resolve (see dig results below). Any ideas on how to troubleshoot whether this is something wrong with our DNS server or something happening higher up with the recursive queries?
