Unable to ping device from Windows 2003 server

I have a very similar problem as described in http://www.experts-exchange.com/OS/Microsoft_Operating_Systems/Server/2003_Server/Q_21837412.html .

Running Windows 2003 Server Standard + SP2 as AD Controller, DHCP, DNS, Echange, WINS.
The roles of AD, DNS and WINS also are hosted on a second server (Windows 2000) where I don't have the problem.

The device I am trying to ping is a built-in controller for a time tracking device (people badge in/out). It only has an IP address, no host name (doesn't register itself in DNS).
All hosts are in the same subnet (no routing or firewall involved).

From the Win 2003 server however I can not ping the device. Telnetting to the device however works fine.
Using Network Monitor I can capture the outgoing ping request (from server to device), but no response.
Pinging works fine from other PC's, servers, switches (Cisco).

I already cleaned up AD, DNS and WINS (on both servers). In DNS there were some reverse lookup pointers using the devices IP address, but tied to a different hostname. All services were restarted several times. The problem server was even rebooted.

I tried the suggested solution in above link, but that did not help. Didn't expect it to, since name resolution is (as far as I know) not involved when pinging an IP.
Looked in the switches whether anything was blocking (e.g. port security, VLAN's). Checked all MAC address table lists if they match the servers and devices.

This has been bothering me some time now. It's not really crucial, since the server in question does not need to communicate with the device. I would like to know however what is going on.
Any help appreciated.

Can you ping the device from any other machine on the network? If not, then perhaps ICMP traffic is blocked on the device. Also, is RRAS installed on the server?

Try to disable windows firewall and try it...

Like I said in my starting post, ping works fine from any other machine in the network and there are no firewalls involved.

The server is not a RRAS server.

If you need more info, please let me know.

Okay - what about if you traceroute to the device - how far do you get before it times out?

I would suggest that you enter the IP address in to  the local host file of the 2K3 server (c:\windows\system32\drivers\etc\hosts).  Since there is no host name to register in dns, and since it looks at the local host file first, this will not cause any issue(s) with your network, but will give the 2K3 server a way to communicate with the device.

Hope that helps.

Ummm, msincorp I'm sorry, but I completely disagree. didi79 cannot ping the device by IP address, so adding a host record for this device is not going to achieve anything at all as the issue here is not name resolution.

Traceroute to the device doesn't come up with anything, timeouts from beginning to end.
However the default gateway is ping-able. To my understanding, traceroute should at least report the default GW.

On that matter: The default GW = core switch (3750E) and the server is directly connected to it. There's one more switch (2960G) between the core and the device. Maybe the problem is somewhere along the path...

One other thing: The ARP list on the server mentions the device's IP and MAC address !!

Hosts file binds IP adresses to names, so indeed this is irrelevant here.
