I only use shared networking and I run in to problems sometimes when, inexplicably, my XP VM configuration switches into Bridged mode. This caused the the network port at my company's office to block the port as there are two IPs trying to access the network at the same time. I then have to have IT call the central network admins to unblock the port. Since I never want to use Bridged, is there away that I configure the VM so that Bridged is never available to switch into?
