Thank you for Reply Yes i am as a client of that LAN. And i want to get all the IP Addresses and Names of the computers connected with the same LAN. I have tried this way for test: using System.Net; String strHostName = Dns.GetHostName(); MessageBox.Show(strHostName.ToString()); IPHostEntry ipEntry = Dns.GetHostByName(strHostName); IPAddress[] addr = ipEntry.AddressList; for (int i = 0; i < addr.Length; i++) { MessageBox.Show(addr[i].ToString()); } But it gets only My Computer's IP Address and another one IP address. I think it is mac address. I have put that IP Address on Run "\\121.245.75.159" but i opens my ShareDocs. Please help me. :-O

Just an idea, but what if you get your own ip address (using the method you described), your own subnet mask[^], and then ping all the possible addresses within that subnet? The link (labeled "subnet mask" will also allow you to ping the other addresses as well). This will work assuming your subnet mask limits the number of possible ip's to a reasonable number (probably less than 2^8 is reasonable.) Hopefully someone else will offer a more efficient way to do this for you, but in the meantime this will work.

Sounds like somebody's got a case of the Mondays -Jeff

You'll have to go through the entire range of IP addresses, PING each one to see if it responds, and if so, resolve that IP to its host name. There is no one function that you can call to give you the entire list.
