Check for open port on a remote station

Hi... I doubt about writing this on the Networking forum, but I preffer a pure-Win2K help.

I have an application installed in my clients pc's. This application uses TCPIP to talk to the server and send some information. From time to time this application stop responding and, because there is a lot of clients, it can take me days to note the malfunction pc.

How can I know if a specific tcp/ip port on working on my client pc´s?

Hi guys and thank you for your help. I was using those and other tools and found no port open were expected.

Read here and there, I've found that this application uses the IPDS (Intel - Ping Discovery Service). That's maybe the reason the previous tools didn't find the opened port.

Now I'm needing documentation about the IPDS and, prefferible, how to use its DLLs.

Any help would be appreciated.

Intel Ping Discovery Service (PDS) is a service (pds.exe)

This service allows for discovery of products on this machine. Applications register with this service, along with an APP ID (Such as LDVP) and a packet to return in response to ping requests (pong packet).

Description: Intel Ping Discovery Service (PDS). Part of Intel's LANDesk Management Suite 6 and the Common Base Agent (CBA) - used for communicating between the core server and managed clients. Will start the dial-up if installed and enabled.
Obligatory: User's Choice
System: No
Developer: Intel

Thanks Samll Bee.... what I need is to do a normal ping to the station. Then, if answered, send the IPDS ping and wait for the pong packet. This way I can detect the stations with the problem.

How do I send the ping at the IPDS "style", and read the pong?
