Re: Messenger Service window popped up on my Serve said by psloss:
But when I ran a net send from a Windows 2000 system to a Windows XP box, Ethereal shows that the message was delivered via udp/135! I'm going to now test to see if these messages can get through on udp or tcp 135 without NetBIOS running...so there may be a couple of different ports that need to be blocked.
I just "verified" this on an XP Pro setup. The XP Pro system has NetBIOS disabled and is not listening on tcp/139 or tcp/445. It is also not bound to udp ports 137-139 or 445. I can still push messages to that system with net send from a Win2K box. I haven't tried an NT4 system...
Can anyone else test this?
Thanks,
