That's my first guess too.

Ashley should read up on "path MTU discovery" and the problems that  
are associated with it.

A heavy-handed approach would involve contacting one of the afflicted  
clients, and modifying the MTU of your server's (or the client's)  
Ethernet interface to something like 1400. If the problem disappears,  
you have (most likely) discovered a path MTU discovery problem.

The side effects of reducing your Ethernet interface's MTU are mostly  
that traffic will be (slightly) slower - you'll need more packets to  
transmit the same data.
