  Combining so many functions on a single machine is not really recommended.
 It *can* work, but excessive load on one service can show up as poor
response (or even failure) of another service, and so sorting out cause from
effect can be quite difficult.

  Can they ping the 2KAS machine?  (by name?  if not, by IP address?)
  Can they ping the address that the 2KAS lists as its default gateway?
  What happens if they try to ping www.yahoo.com?

  Not just physical connection, but some kind of local name resolution (DNS
or broadcast or (possibly) 'hosts' file).

  And yet, there's no real indication that there's anything wrong with the
first address.  It might be useful to have more info about what fails and
what doesn't.
