I googling a lot n finally i configured all the options once againg through RSCongfiguration Manager.
I have the issue with email settings.
U need to configure email setting properly.Other wise u would get the following error.
"An existing connection was forcibly closed by the remote host at System.Net.Sockets.Socket.Receive(Byte buffer, Int32 offset, Int32 size, SocketFlags socketFlags) at System.Net.Sockets.NetworkStream.Read(Byte buffer, Int32 offset, Int32 size) "
Once u did every thing properly u should Subscription through email.
