GOOD LORD!!!

Apparently those IP address for my ISP DNS servers are no longer valid. 
I changed settings on all machines to obtain DNS automatically and
everybody is up and running.  Been using those IP addresses for over 5
years!!!

I just spent 2 1/2 days of a 4 day weekend on this.  :-(

I really appreciate your help in resolving this issue!!!!

Again THANKS!!
