Are you sure it not actually a DNS issue?  Check the URLs being sent back
by the cat app. Do they contain the FQDN you are expecting?  Are you able to
reproduce this issue on multiple IE machines?  Have you tried running
wireshark on the IE machine to watch exactly what it is doing on the wire?

Good luck
