We have a MS Windows based client application which resides on a local LAN. It accesses and receives data from a WAN over multiple protocols. They are UDP/X.25, TCP/IP and HTTP. It is a high transaction environment.

The client either hangs or closes if there is a problem with accessing or recieving data over the WAN.  However, the exact nature of the problem is not known.

We are looking for a place to start to troubleshoot the problem assumed to be the network. Where do we start? How can we determine what is happening with the data access or receive before or at the moment the application hangs or closes?

What utilities are available for this type of troubleshooting? Do you have to know data coms to use them?
