To Nikhil_CV, F4E, lmacri and everyone else who replied to my post(s): Thank you for taking the time to address my problem with your thoughtful and informative posts.
I will submit Autokms for analysis as instructed. Adding three teenage kids to two desk tops, two laptops, and three iPads results in what I can only describe as a massive headache. I thought I had a handle on things, and in a way, I still do, though I am only 97% effective in controlling things. Only six months ago, nearly every device was routinely infected by all sorts of bad things.I grew tired on wiping HDs, reinstalling software, and yelling at my kids. They seem to have gotten the message - almost.
Anyway, while I sincerely thank you all for your help and advice, I am still stuck with my original problem - NPE still hangs at "checking internet connectivity." So, I compressed and sent NPETraceSession.etl to Surendran. I am hopeful he can determine what is causing NPE to hang. Otherwise, I suppose I will need to reinstall NIS.
Regards to all and have a great weekend!
