Hi guys. Thanks to all of you for replying posts. string PCName = Dns.GetHostEntry(Request.ServerVariables[ REMOTE_ADDR ]).HostName; Dns.GetHostEntry(Request.ServerVariables[ REMOTE_HOST ]).HostName; both are working fine on same Network and on desktop Browser but when logging from mobile browser it gives SocketException. No Such host is known Let us know how to fix this exception.

As far as I remember in order to get: Request.ServerVariables[REMOTE_ADDR] Request.ServerVariables[REMOTE_HOST] Request.ServerVariables[REMOTE_USER] you have to enable Reverse DNS Lookup for you IIS. p.s. atm I'm not able to test it myself so I'm not quite sure if this will solve ur problem Thanks stackoverflow.com team for your efforts.
