Whoops, didnt see the double post
Ok, first with your friend.
Are Mandrake and XP on the same box? Different boxes? Is he running it via VMWare?
If they are on the same box, then he will not be able to do telnet mandrake and have it work IF he is running it on the same box via VMWare then this *could* work. IF they are on different boxes, then he somehow (possibly accidentally) set it up so that mandrake resolves to the ip of his Mandrake box.
Are your machines seperate? Or at the Redhat and Windows install on the same box?
