Just as Craig suggested, first check the server itself. Can it resolve DNS?, do you have the correct DNS addresses in your IP configuration? Can you do a dig/dnslookup using the servers in your configuration?
Also, I tried opening the link but I was not able to see the picture, but then, it might be my content filtering

Hi,
I have configured one of my DNS servers to run the dns test native to xymon. I have the directive "dns" specified in the bb-hosts file and the test shows up as a column however the test does NOT perform a lookup of the servers dns A record as it should. All i get is the "Service DNS on SERVER.DOMAIN.COM is OK (up) and then a graph immediately below.
I have also tired using the dns=a:server.domain.com with no luck either.
I have posted a screen shot on PhotoBucket - http://i761.photobucket.com/albums/xx256/mfisher_xymon/dns.jpg
Does anybody have any insight as to why the dns lookups are not being ran?
