Thanks everyone for the info. Sounds like it's really nothing to worry about. I'm so new to networking stuff beyond the basic that I'm not always sure what's good or bad.

I suspect instronics is heading down the right road when he suggests the modem might be the culprit. I have my Smoothwall red interface attached to my cable modem, so that might be the issue. Either way, sounds like it's not a huge deal anyway. So much to learn.........

Thanks everyone!!!
