confirm which Desktop to connect to. If you are launching a Windows session,
you will need to supply an IP address and the Domain name. If you are
launching a VNC session, you will need to supply the VNC IP Address and
Display Screen. If connecting to a Shadow No Machine connection, you
shouldn't have to supply any other information than the fields above.

checking this box will disable SSL Encryption .
 Disable ZLIB Stream Connection -Checking this box disables ZLIB
stream compression. This removes the overhead associated with
compression VPN network traffic, lowering server processor usage.
 Disable Direct Draw -This option is available for the No Machine client

the GDI engine. This can resolve later conflicts with other Windows
applications that may use DirectDraw. This also results in a much better
performance using Windows Vista.
