dns problem with browsers only?

[beaman]

Hey,

Has anyone seen this before?  pc's can use short name for telnet, ping, and
nslookup.  But when they use a short name in a browser (http://intranet),
it doesn't.  The web page is not displayed and they get a 500 error.  But
when they use the FQDN (http://vm.cfsan.fda.gov) or the ip address
(http://150.148.80.40), bingo - it works!  We have tried going to different
web servers (http://intranet, http://updates) and using different browsers
(netscape, hotjava, ie), but we get the same behavior.  nslookup looks fine
for nslookup vm and nslookup 150.148.80.40.
