How do I change MTU in WinXP and Server 2003?

I am having some issues with data moving between sites connected with a Cisco VPN. Cisco has advised me to change the MTU setting on an XP workstation as well as one of our Server 2003 boxes. However, he didn't know how to do it.

I've looked at the NIC settings for these particular machines and don't see an MTU setting. Is there a place in the registry or some other way to do this?
