Hi Brian,
 
Are you using a dial up connection or the dreaded PPPoE? Its very
unusual for a packet filter to conk out without the help of dialup or
the PPPoE kludge :-)
 
Thanks!
Tom

        Along these same lines (well not really..but close)

         

        It would appear for some reason our ISA Server (win2k sp3/isa
sp1) all the sudden decided it was going to block all incoming traffic
on port 25.

         

        The only solution found was to disable, and reenable the packet
filter allowing SMTP in/out 25.

         

        I found this very odd.
