I have a problem with sharing my Internet Connection from a Vista host to a
XP client in a wired network. Before installing Vista, the connection worked
fine on a XP host.
Right now, on the Vista computer, if I scan the network, the XP computer
appears in the list, so as far as I can see all the cables are ok. I have ICS
activated on the Vista host, but when I try connecting from the XP client to
the host, I get "Limited or no connectivity", because it can't assing any ip
to the XP client or something like that.
Any suggestions?
Thanks,
