[Munoz-Persinger, Axel @ CSG - CSE]

Thanks everyone for the help; we ended up just changing the address on this as suggested and it works flawlessly.

Thanks,
Axel

+1 for changing the address in dns

if you don't like/can't do that option, add
  search XYZ.l3t.com
in resolv.conf so that the first dns lookup for foo is foo.xyz.l3t.com

see  http://man7.org/linux/man-pages/man5/resolv.conf.5.html
              The search list is normally determined from the local domain
              name; by default, it contains only the local domain name.
              This may be changed by listing the desired domain search path
              following the search keyword with spaces or tabs separating
              the names.
