Earlier today, I heard Bob O'Donnell, host of the "O'Donnell on Technology" radio program and the web site
EverythingTechnology.com, in response to someone else's question on a home network problem, recommend posting the question in the online forums of the web site
PracticallyNetworked.com. At first glance, that looks like a very useful recommendation.
Thanks so much for all of the advice. I'm just now getting back to the computer today, so I'll try everything that's been suggested.
Again, thanks -- I appreciate the help.
