We have DNS setup and it seems to work fine with one exception. When
searching our own name on Bing ("mhtn") it points to "mhtn.com" not
"www.mhtn.com". Within our network clicking on this link fails saying it
cannot resolve "mhtn.com". Outside our network it works just fine.

My conclusion is that something in our internal DNS setup is set wrong. How
can I create a resource record to correctly resolve "mhtn.com" the same as
"www.mhtn.com"? Is there some forwarding I have setup wrong?

Thanks in advance!
