hi all
i am developing a multiuser environment with 4 com servers each connected to one terminal server. each terminal server is serving 8 clients which are thin clients.
i need the com server ie the transaction server to track the no. of clients are logged on to it in turn i want the comserver to return an id to the application which is stored in the com server. the id will be used to identify the client for future transactions which it will be doing to the server.the com server must keep count of the no of clients connected to it.this will be usefull to know whether any of the server is down.

when the user starts the application and starts using the components on the server it must immediately tell the user its idno. extracted from the server

if anybody has any suggestions on this topic
thanks in advance
