I have all the ports open that are listed in the following article but
that does not seem to be enough.  I have also tried opening all ports.;en-us;278339

I do have ports 135,137,138,139 and 445 blocked at the router and the
option of opening them up does not exist, nor does the option of using the
ISA server.  These are the "netbios traffic"  ports.  Can MS Exchange
Server work without having to open up these ports?

best regards
