I bring up these questions simply because I've had similar issues, not with UT, but other appliances. How about a straight-through cable ? I know that should not matter nowadays..but you never know...
Just a couple of thoughts, seems like all the other bases have been covered.

I've tried it both ways, using the same and different ports on the switch. I've also cleared the ARP cache and MAC tables after making the switch to ensure that the 6509 doesn't have any leftover entries for whatever reason.
This seems to be a higher layer problem. We have no problem with IP connectivity, but DNS names don't resolve. Something's happening at a higher layer to impede that traffic.
