I have a home network with 5 or 6 PCs on it (depends on notebook connected). Router is a wired SMC Barricade and all the PCs (except notebook) use Win 98SE. All the connectivity has been working well for some time (>1 year). However my daughter's computer lost connectivity with the lan and wan recently while I was out of town - she tried to correct this by stumbling through the internet and network settings in control panel. Because the disconnect was so complete I replaced her network card (d-link rev A) with a d-link rev C. This successfully brought back LAN connectivity but not WAN - at least not http. I can ping other LAN computers, the router and external URLs but I cannot get anywhere with IE explorer or Outlook (full or express). I've confirmed that all settings are consistent with the other computers on the LAN but feel I must be missing something. Her permissions and firewall settings are fine and the problem persists no matter how generous I am with permissions or firewall off. I've also tried specifying DNS, Gateway etc in all combinations. TCP/IP is the only protocol enabled (Netbios is checked). I dread re-installing windows but I feel I've run out of options. Any ideas obvious or not would be appreciated. Sorry for the length!
