Lars, Thanks!
I'm beginning to understand. I have only a single computer with cable
modem, so maybe Linksys is looking for other computers on the network
and not finding any. Maybe my Linksys is not configured properly, but
I've gone over their manual and settings (internet site to change)
lots of times, and I think it's right.
I'm confortable with computers in general and have no problem or fear
about editing the registry, but I couldn't get to the site you
indicated above. Connection refused to support@microsoft.com
I had no problem connecting to your website, which is very
interesting, by the way.
File and print sharing are disabled.
Thanks again.
Jack
