W2K networking question

I have a question regarding networking in W2K, but don't
have a lot of information.

There is a print server with address 10.1.2.99 and a
default gateway of 10.1.2.1.

Trying to ping or tracert the print server doesn't work
from workstation 10.10.1.57 with a default gateway of
10.10.1.1. However, setting up a standard tcp/ip port
and adding a local printer to that port works.

Does W2K (or possibly firewall software/hardware) disable
ping/tracert when crossing networks? If not, why does
ping/tracert not work?

Thanks!

You most likely don't have a rout to the 10.1.2.xxx
network from you LAN. You'll need to do a route add
command on the local machine or even better your router
needs to have a route added so that it can pass traffic
between the two LAN's
 
It sounds like the router between these two networks doesn't allow ICMP through. Windows 2000 by default does not block
ICMP.

Thank you,

Michael,

Thanks for you answer!

So, assuming the router is blocking icmp packets, the reason why I can set up the tcp/ip port is because W2K is using tcp (which the router is not blocking); whereas the ping/tracert commands don't work because they use icmp (which the router is blocking)?

Hi Paul,

Yes it appears that the router is not blocking the TCP port, but is
blocking ICMP.
