I have a Java Swing application on a HP ProLiant DL380 G7 Server.The OS on the server is MS server 2003. My users connect to the server via RDP and start using the application. But today suddenly when the user started the application and click on a menu it is not responding. I want to know is it server issue or software issue. I doubt it is software issue as it is working for the past many years. I checked the System Management Homepage of the server and there in the report it is showing all is normal with the server. what could it be I am dumb stuck.Please help,.
