Hi, at first, sorry about my english it's bad: thanks about your tips. I have a problem with my app, i'm writing an client/server app and client stations connected to internet, now i want to know how can i check that client stations are receiving data from internet or not. if i could not explain my mean then see below: sometimes when i want to go to yahoo.com, internet explorer told me that - The page cannot be displayed - this what thing that i need to know(client station is not receiving data from internet). this message occur when internet service provider is not working well, so any request of users will show that message, now i want to write an client/server app that client stations send their status rapidly to server app. with this i'll know whitch station is not receiving packets from the internet. another quetion is how can i restart,turnoff a client from server app. sorry, about my text it's very poor.

I reformulate what I understood: 1) You have a client/server application (I'll assume your use socket and TCP connections to communicate bertween client and server since you ask in a winsock newsgroup). 2) Your server is available from the internet, that is it has a public IP address 3) The client workstations connect to the server thru their internet access 4) Sometimes the client can't connect to the server 5) You want to know if the client connection is up and running 6) To achieve (5), you'll have your client application connect periodically to the server, just to verify the connection. 7) The server will "rememeber" when each client has connected the last time and if this is too long since last connect, the server will trigger an alaram (maybe will send you an email ?). Did I reformulate correctly ? What are you using for your communication ? Which component or which API ? Have you designed both the client and the server ? Which protocol are you using ?
