I've overcome the problem by shutting down ZA firewall on the client PC. It seems to me that since this PC connects to the internet via the firewalled host PC, then I shouldn't need both firewalls. However, I've often read that firewalls on both PC's are desirable (if not necessary?). Has anybody any comments? Thanks.
I next need to configure the file & printer sharing facilities. When setting up the network, I followed the advice of the wizard to leave those unil later. Advice will be welcomed. Thanks Again. Mike.
