My problem was coming because same certificate has been used for client authentication (client / server side). To run my code successfully i need a client certificate and server certificate from same CA or windows server 2003 / 2008. Is it possible for someone to provide client & server certificate from windows server 2003/ 2008. Then using those certificates mapping can be done.

Certificates do not contain credentials. Certificates are mapped to accounts and the TCB will give you credentials if you present the correct certificate and prove you have the private key. To check the certificate is valid open it with the right-click menu. If you are using it as a client certificate and expecting it to work to authenticate you in a TLS session you need to consult whoever owns the server since they will have to set up the mapping.
