Class Description:

    ISRPC is the class definition for RPC interface used by Internet
     Services admin.
    This class provides methods to enable and disable protocol over rpc,
     enable security over rpc, and other rpc related tasks.

Private Member functions:

    SetSecurityDescriptor : builds security descriptor to be used in
        different RPC calls.

    AddSecurity : enables security support provider over raw
        non-secure protocol such as tcp/ip.

Public Member functions:

    ISRPC : class constructor.

    ~ISRPC : class destructor.

    AddProtocol : adds another protocol to the binding list.

    RemoveProtocol : removes a protocol from the binding list.

    StartServer : starts rpc server.
