Hi, I run an udp web-based application on windows server 2008 and I am having trouble when my computer is "idle" (for like 30 minutes.. I disabled the screensaver, still has the issue). Basically sometimes this application crashes and it is auto rebooted. However if the server reboots when my computer is idle, i can't reconnect to the application. It works if it was started before the computer was idle.. I can freely connect and disconnect... But if the app reboots and my computer is idle i cant connect. Once i "wake" it i can connect though... The computer is not asleep, it has just not been used for 20 or 30 minutes. why does this happen?

Hi crasx,you need to handle this specifically on your application.for TCP protocol there is a api called tcpkeepalive which will send heartbeat packets when the connection is idle, i would suggest to implement the similar concept.why would your application crashes if it is idle ? , If it is a custom app which you have built you need to debug to understand the code , if its a 3rd party vendor app , then you need to contact him to let him know the behavior AFAIK there are UDP keep alive packets , but it depends how you are managing the socket connection
