    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    Apparently those IP address for my ISP DNS servers are no longer valid.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!!
