Thanks Tacit. I know how on a Mac. How do you find it on a PC? I got into his network settings and saw iirc four ip addresses. Would it be IPv4 server? I know nothing about PC's and am nervous about screwing something up. The more I get into this the happier I am to be a Mac user. This process took me 5 minutes to do at home on my cable internet. I've been trying for 3 hours at his place to do the same thing.
