Have a client with a multi-os network that suddenly went down. They are using a hub and have anything from windows98 to xp home. They just added a new windows xp home machine. Everything worked fine. they then added write access to the new machine and shortly thereafter the network disappeared. the old windows xp home machine and see and access the network but none of the others can even see the network. the ip addresses are fixed. Any ideas before I head off into the sticks? ( it's a campground )
