I need to lower the MTU size to 1300 or so to get a network app to work.
I've read almost every post on the subject, but none of the advice works
(works in XP, but not Vista). Does anyone know how to change the MTU size
in Vista (32-bit)?

thanks.

Have you tried using "DrTCP" found on broadbandreports?

http://www.broadbandreports.com/tools

But changing the MTU size on Broadband/Network connected machine may
severely impact the performance of the machine.
 
Dr Tcp did not cure me. However, It turns out that another old app,
tcpoptimizer.exe, does work. It changed a large number of registry settings
but at least it worked (after I allowed it to update the network card
settings).
