Dear friends, i am currently working on a module which lists the IP address of all the active systems in a LAN. The process continuously runs and updates the IP addresses(in case logged in or log out). I have used timer to update it. Now i need to check if a remote system is logged in or not. So if you know please do tell me what should be done to check if a remote system is logged in. Thank you(in anticipation) Shalumalu
