Thanks for your suggestions.
I should have mentioned in the original post that I had already run the Microsoft HOST file "fix", even though the HOST file on the PC did not have any extraneous entries. The 'fix" did replace the HOST file, but the problem remains.
I do not use any proxies, so that doesn't appear to be part of the problem.
The fact that the "google.com" name resolves to what appears to be an incorrect address (when being "pinged" from within the CMD command environment) would seem to indicate that the problem is not browser related.
I am hesitant to download your suggested diagnostic tool, as it isn't one that I have ever used or even heard of.
I do want to thank you for taking the time to provide suggestions.
