      I am having Oracle 11g (Release running on Windows Server 2007 SP2. I am trying to connect to this server from my system using SQL Plus command prompt. (Dedicated - redirect (client and server are on different computers)

      I am getting an error: TNS-12518: TNS:listener could not hand off client connection.

      When I checked the listener log in the server machine, these were the errors:
      TNS-12518: TNS:listener could not hand off client connection
      TNS-12560: TNS:protocol adapter error
      TNS-00530: Protocol adapter error
      32-bit Windows Error: 203: Unknown error

      tnsname.ora entry in the client side(my system)
      (ADDRESS = (PROTOCOL = TCP)(HOST = md1svcvwm01)(PORT = 1521))
      (SID = BAM637_SERVICE)
