'Change the MTU and RWIN Settings' in Vista?

My MTU settings have been giving me major problems since an upgrade to my ADSL connection (in the UK). Basically without setting things manually I have no access to various web sites including everything Microsoft-related (e.g. Windows Update).

I have used 'DrTCP' software to set my MTU to 1430 and my RWIN to 65535 for all my Windows XP PCs, but I've now put Windows Vista RC1 onto one of my PCs and it can't get to Windows Update etc., and DrTCP is not compatible with Vista.

Does anyone know exactly how to set my MTU to 1430 and my RWIN to 65535 in Vista, for my network connection? Without this info my Vista install is basically useless as I can't keep it up to date with Windows Updates etc. :(

Try only to reply to the question asked, please. Original poster was very concise and specific, and telling him how to access or update drivers is not what he/she was asking.

You can change the MTU settings in vista using the following command from the command line as an admin...

netsh interface ipv4 set subinterface "Local Area Connection" mtu=1300 store=persistent

If you just want to see what your settings are you can run.

netsh interface ipv4 show subinterfaces

I copied that line from an MTU setting I was changing at the time, obviously you would use 1430 instead of 1300. Just clarification.

Nailed this before answering my own problem too here. get up command prompt (cmd) use ipconfig and find out what network connection your using, usually something like local are connection or wireless area connection take a note of capitals and so on then type this in netsh interface ipv4 set subinterface "Local Area Connection" mtu=xxxx store=persistent changing Local area connection to whatever it should be and change xxxx to your new mtu value i struggled for about 8 hours with this and then this sorted it!!!!

You're still using a pre-release version? (RC1) It will be useless before too long anyway as it'll probably be expiring in a little while.

So does that mean the correct commands to set the Local Area Connection to an MTU 
of 1460 and the RWIN to 65536 would be as follows?

netsh interface ipv4 set subinterface "Local Area Connection" mtu=1460 store=persistent
netsh interface ipv4 set subinterface "Local Area Connection" rwin=65536 store=persistent

Nope, the RWIN command does not exist. Correct commands are: interface, mtu, subinterface, store (active or persistent). You can´t store a persistent value for the RWIN. Gonzalo
