I’m running a development server virtual machine on my Vista laptop using Parallels. Trouble is being on a laptop sometimes I’m on the road so a Host only network suits me, but other times I’m at home so I want the guest machine to connect to my home network. Up until now there has been A LOT of screwing around each time I leave and come just change network the network settings…

First of all I tried the obvious Internet Connection Sharing throws some “(null)” error - Google forums to read about it. Bridged networking not that I really understand how this would have helped? this but someone made mention of it… I don’t profess to being a professional at this, BUT the following configuration made my life a dream.

Now I just simply change my the Network in Parallels from “Host only networking” to “Default adapter”..
