Clearing the connection status depends on where the state of the connections are maintained. It might be possible that the connection states for these IPX connections are stored in a file? If so, you can just remove the stale files.

If the IPX connection state information is being preserved by a process, which should terminate on idle, but does not; then you can kill the process manually.

So, the trick to solving this puzzle is to do some homework and find out where the IPX connection state information resides. After you discover where the connection state info is managed, then you can decide the best way to clear the state information.

You are correct in observing that all robust implementation of TCP/IP manage state information in the socket structure and TCP does not have these problems. It is interesting that IPX does. Please let us know what you find out.
