VNC viewer not connecting to MAC from PC

I have a VNC server running on a Mac. When I try to use a VNC viewer, it says "no matching security types".

Is there any other software which can connect to a Mac like RDP?

If iI use screen sharing from another Mac, then it works but not from VNC.

EDIT: I am using:

• Leopard 10.5.7,
• vnc VIEWER 4.1.3,
• nothing installed on MAC,
• On Same LAN,

• From memory you'll need to either use a v3.x viewer or configure the one you have to use the version 3 protocol. How depends on your viewer but it should be covered in its help file or web site.

• Try TightVNC to connect. It seems to work when the free edition of RealVNC does not. http://www.tightvnc.com/

  I've also found that the VNC viewer will konk out when connecting to the Mac if the viewer is not running in millions or full color mode.

  Master : I tried it and it says , server did not offer supported security type

  Master : It also says , no configured security type is supported by 3.3 viewer

  John Gardeniers : That's because of the version conflict I referred to in my answer.

  Master : I installe VNC enterprise view , finally it got connected but looks weired like only 16 colors or something

  Master : Now TightVNC is also working but the problem is color , TightVNC also shows only 256 colors

• You can encounter this problem if the server does not have a password configured, or the server is running with integrated authentication and you are using the free VNC viewer. The free VNC viewer does not support some of the newer authentication methods.

• I'm not sure which VNC server you have running on your Mac, but you can use the built-in one.

  Apple menu --> System Preferences --> Sharing --> Screen Sharing

  Make sure that its configured for VNC access with a password. Then try to connect to TCP port 5900 with a VNC client on your PC.

  To answer the other question: VNC is the Mac answer to RDP, actually. Even the commercial "Apple Remote Desktop" package ultimately uses the VNC protocol.
