I have just rolled out my Win2K server, with a setup that was based off my
NT4 server. Everything went pretty well the same except for the network
properties for my servers interfaces.
I had port filtering enabled on my NT4 system and I see the Windows 2K
server has the same window. However I have found that after enabling port
filtering and setting it to deny all, except for the ones I know I want ( 20
/ 21 / 25 / 80 / 110 ). However after implementing that a bunch of the
services started crapping out on me and or started generating tons of
Can anyone who is also using port filtering tell me what settings they have
As near as I can tell the NT4 system gets by it, by just looping back
requests internally on the server. Where as the 2K system actually sends
the request right to the level of the interface and then is looped back as
long as the port is available.
One last thing too...
I want to run netbeui on my LAN but NOT on the WAN interfaces. I see I can
disable it by clearing the check mark on the interface services and protocol
list. But I can not find a way to remove it totally without removing it
from all of the interfaces on my server.
By the way.. services I am running on this server include....
SMTP -exch 5.5
POP -exch 5.5
NNTP -exch 5.5
Oh and yes a Half Life server too, but don't worry about that :)
Thanking you in advance for your feed back.
