2 Win98 2nd edition PC's were connected directly via a cross-over cable and an onboard LAN on PC 'A' and a network card in PC 'B', and they shared their drives. I changed the cross-over cable to striaght through and used it to connect PC B to a new pre-configured DSL Router. I connected PC A to the router via a new cable.
I configured IE6 and Outlook Express to work fine with the router (192.168.1.1) using fixed ip's PC A = 192.168.1.2 and PC B = 192.168.1.3. I tried using DHCP but althoug it was enabled the connection did not work without the fixed ip's (that might have just been on PC A) - first sign of trouble.
With the internet connection working, I found that PC A could ping PC B but B could not ping A, and PC A could not see the workgroup in Windows Explorer|Entire Network - not icon. Also the update of IE6 to SP1 appeared to fail.
I've tried removing tcp/ip and client for Microsoft Networks on PC A and rebooting, but each time it is still there. I'm thinking the error lies with PC A, but not sure where to go from here.
