    These were previously networked using D-Link router (broadband/cable). Now
    I have a wireless Level 1 modem/router hooked up to DSL. Both computers can
    access internet, but neither sees the other. I've spent hours trying to fix,
    but am having no success. I have McAfee antivirus/firewall. I'm usually
    pretty good at these issues, but am stumped and frustrated over this.

  2. Can you ping each other by IP? If not, try to start both OS with clean boot
    for troubleshooting.

    It is more like that the McAfee was "trusting" to older D-link
    router's IP address. Check on each McAfee configurations and tell
    each to trust the new router's IP address.

    Also, if you are using the wireless "network" part, you may need to
    trust the wireless network name (known as SSID.)

    I already tried disabling the firewalls. Tried the ping test, it failed. I
    think it's something simple, like the router is not configured correctly or

    Have you looked inside the WiFi router settings? For example, Linksys router
    has a setting to enable client isolation (I can't remember the exact term).
    Look for something similar in your router.

    I had a similar problem between a W2K and XP Pro machine. As it turned out,
    the Winsock was corrupted. Diagnostic and troubleshooting info can be found

    One symptom not mentioned is that the Routing and Remote Access Service
    would not start. Try: net start remoteaccess from your command line. If it
    doesn't start...
    Hope this helps!
