I always had ports 137-139 blocked, and I still get these pop-ups.

I'm a bit reluctant to block port 135 because it seems to be needed
for Exchange. Similarly, I think port 445 is used during logon over
our VPN.

Does anybody have any experience running an NT network where ports
135/445 are blocked at the firewall?
