Cannot Ping an IP Only from One System

Windows 2003 Server, Windows XP. I have a very peculiar problem. All the
systems in my network, except two, can access (ping) two of my network
printers. I have a new Dell server and my desktop station that cannot ping
these two printers. The server and desktop can ping other addresses and
printers, just not these two. It is not the switch I am plugged into, as I
have tried my laptop on the same ports and can ping everything. What might
be causing this problem of two systems not being able to ping just two
addresses?

P.S. I ran into this problem as I was trying to connect my network printers
to my new server. Two of my four printers connected just fine, but two did
not. That is when I tried the ping and found it did not work for the two
printers. Help!

Dont mean to insult you by these questions but have you checked:
1. Firewall on both ends blocking ICMP requests
2. The machines are on the same subnet, have the correct gateway
3. The Printers have the correct subnet/gateway assigned

Dear Mark:

No insult taken. Thanks for responding.

1. Firewall is disabled on both system that cannot ping the printer.\
2. Both machines (and printer) on same subnet. The two machines that
cannot ping and the machines that can ping the printer have the same subnet
mask 255.255.255.0 and def gateway 10.251.0.254
3. The printer has a different subnet mask (255.255.255.224) and a
different gateway 10.251.0.33. However, why can all the other systems ping
the printer but not two of the systems, even though they all have the same
subnet mask and def gateway defined?

I AM GOING TO TRY TO FIGURE OUT HOW TO SET THE SUBNET MASK AND DEF GATEWAY
ON THE TWO PRINTERS TO MATCH THE WORKSTATIONS ANS SERVER. ANYBODY KNOW HOW
TO DO THAT ON AN HP LASERJET 8100N AND A LEXMARK OPTRA LXI?

The problem appears to have been that the two printers in question had a
different subnet mask (255.255.255.224) than the rest of the net
(255.255.255.0). When I reconfigurred the printers (an HP 8100N and Lexmark
Optra L) to the proper subnet mask, then I was able to access the printers
from all systems. What baffles me, but for now is moot, is why only two out
of our twenty systems had a problem accessing the printers.

Lesson learned:

When you place a new server on your net, and you want to make the new server
the print server, make sure that your printers are configured with the right
subnet mask and that the printers have their default gateway set to the new
server's IP address.

Im glad that worked for you. The one thing that could solve the mystery is
WINS. If the printers register themselves in WINS then WINS was resolving
your requests on the other machines... Did you place the default WINS
servers in the Network Connection on the new machines?

The mask would cause only certain machines with certain addresses to not be
in the same "logical" subnet of the printer, while other machines would be
in the same subnet and would work.

For example,...If the printer's IP# was 192.168.1.18 / 255.255.255.224, then
any Client with an address below 192.168.1.30 would work fine,...anything
over 192.168.1.32 would not. This would be the case even if the Client had
the correct mask of 255.255.255.0

To expand on what Phillip said, you would need to look at how the VPN
connections are configured. In general, each remote site has a route to the
corp network, and corp has a route to each remote site. In that case, each
site can see the corp LAN but they cannot see each other. It is what is
known as a hub and spoke setup. There is no "rim" on the wheel, so sites
can't see each other.

To route between sites, each remote site needs a route for every other
site via the VPN link to the corp site. Since corp has a route to every
remote site, it routes it back up the correct spoke. Of course you can use
one route per site if that route covers all of the remote sites and the corp
LAN. eg if each site is using a 192.168.x.0/24 subnet, 192.168.0.0/16 covers
them all. All 192.168 addresses go to corp, then it forwards those for
other remote sites as required.
