Hello there,
I work for a rather large organization and we have a little over 1000 pc's. Now we have just moved most of our sites to a private VPN and we have been havening problems with out MTU sizes. Since all out PC's MTU sizes are the default 1500 bytes when they hit the router they have to be fragmented into 2 packets cause of the VPN overhead. i was wondering if there is any way that we could change the MTU size on all the computers all at once, just not one at a time. I have been looking at a way to deploy a MSI with the correct registry changes, but that also hits a problem. In the registry every interface ID is different. So I don’t think I can make 1 MSI file to cover all the pc's we have.

Anyone got any kind of suggestions for me?

It's a registry hack.. there are several programs out there that will change it.

I believe ethenet MTU is 1492.. change it to 1450 and you'll be safe though.
