I have a home network set up as follows – DSL Modem Netgear router (RP114) Win 98 PC Win ME PC Win XP PC Everything worked fine until I tried to install some antivirus software on the Win XP PC (both of the other PCs have antivirus SW previously installed). After much difficulty I finally got the sw installed – but my home network no longer worked (sharing still worked but email and internet connection lost). I have since unistalled the antivirus sw on the XP PC. The network now works fine as long as I do not attach the XP PC. When I do attach it, I lose email and internet connectivity on all machines. The XP works fine if I connect it directly to the modem. Any suggestions would be appreciated.

Just a thought, but you could check to see if internet connection sharing is enabled. You don't need it since you are using a router. Disable it if it is running. Also, you could try disabling the firewall temporarily if it is running. Although, that should not affect the other computers. Michael J
