Does anyone know of a way to alter the properties of LAN network interfaces in w2k? I know this is not a purely PERL question but the actions need to be performed through PERL so its kind of relevant. Is there a module for this sort of thing or is there a cmdline util of some sort? I tried netsh which is a little cmdline util found on w2k systems(maybe other win32 as well) that allows you to change most properties of dialup interfaces but not LAN. I am trying to do this because one of my clients has two connections to the Inet, a cable modem and a 384K DSL line. I want to be able to, on the w2k router(dont laugh too hard-its not my call on this one), enable and disable interfaces and moves routes around to deal with line outages that happen semi-regularly. A minute convergance time is more than fine so its not a critical network app. but I need to make it automatic. Obviously I can change routes no big deal. Its altering the states(enabled/disabled) and properties of the interfaces thats proving to be difficult.
