Hello-
I have attached a short thread below. Just two posts. The first is my
problem tit for tat. The second is a solution that makes great sense. Does
anyone know how to accomplish what this person suggests? How to block
outgoing 445 requests? I have this trouble on 3 different networks. I'm
suprised I don't see more online when I search for it. Everything I've
tried in the GUI does not work. I'm sure it's command line. I've tried
netsh firewall set portopening TCP 445 DISABLE. This did not help. This
seems like a great workaround although it is a 'dirty fix' as this person
suggests. Anyone know a real fix?
Thank you.

Hi,
since Win2000 and also in WinXP, when windows networking is bound to
TCPIP, the system tries a network connection to remote IP port 445, and
only if this fails, uses ports 137 to 139. As Win98 and WinME don't have
a port 445 open (and would not know how to handle those incoming network
packets to port 445), WinXP keeps trying for some time or number of
attempts. (I'd like to know where this is defined, because after update
with SP2, this takes forever.)
During these attempts, the printing process seems to be frozen.
So your problem may very well go away if you unbind file and printer
sharing from TCPIP on the WinXP machine. I would like to know whether
this helps.
I can't do this because NETBEUI is not supported on our LAN, but
astonishingly the freezing of the printing process also goes away if I
deny outgoing connections to remote port 445 in the firewall.
Now that's a dirty fix, because the system SHOULD use 445 when
connecting to other Win2K or WinXP machines, and I will allow 445
connections as soon as all other machines are upgraded to Win2K or
WinXP, but until then ... if only someone could tell me where to set the
connection timeout so that the freezing stops after that time
(it's NOT affected by the setting of
HKLM\SYSTEN\CurrentControlSet\Services\lanmanworkstation\parameters
SessTimeout=dword)
