I think you are looking for setx, it is like a normal set but it survives after your computer restarts.

I'm assuming you mean non-volatile system wide variables, if that is the case, you can call reg.exe and add your entries to HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment (reg.exe is available by default on WinXP+)

To execute things on remote machines, psexec is your friend.
