My PC is a Dell XPS 8300 running Win. 7 Pro 64 bit.

My anti-virus is TrendMicro Internet Security Pro. However, I already turned it off, and the problem persisted.

I also tried Methods 1 & 2 above. Neither found a problem.

In short, if I lose my internet access for just a few seconds, when it restores, Windows will then falsely report that it is still down. Once the machine is restarted, the false reporting goes away.

Thank you.
