moving forward
 

Ok, I found the "uninstaller" for Norton...I had version 1 and they only supplied it in Version 1.0.1.

Since uninstalling - so far so good. No issues in the last few hours. So I'll watch it for the next few days till I am more certain.

Thanks for the help.

No Norton on this end. And IPv6 is completely disabled already. Really starting to tick me off - happening in Safari 2-3 times a day. If I use Firefox - never happens.

... OK... I confess to be a network novice, but I recall having the same sort of problem before... And there were suggestions on fixes.... (I apologize if this it dismissed as patently wrong, but without question, it was posted as a solution to the sporadic "can't connect" issues... Then again.... I thought it turned out to be a DNS timing issue that was resolved in an Apple update....)

So anyway....

The fix was to contact your IS provider and obtain the DNS servers they use and enter them into the network configuration on your machine....
