I am having a problem with Fusion with vista VM's on 10.5.6.

It hoses my networking so bad .. that I have no choice but to power out the router -- yes believe me it's this bad because ifconfig with all it's options doesn't do it.

I don't know what's going on .. so am wondering if there is a command that starts the networking afresh .. ifconfig is kind of utility on top of something that gets started in rc.local.
I am just too new to mac stuff that I don't know this basic stuff


If anyone can tell me the beans . I will be thankful.
