Please anyone help on this. Any help will be highly appreciated.

Have you enabled the option in System Preferences? You set it in Sharing -> Screen Sharing, this enables the VNC server under OS X and opens the port for it.

Thanks for replying smith. I have enabled the options for screen sharing but unfortunately it didn't works and moreover i didn't found any ways to open the port(i.e 5800) in mac. could you please help me what to do next? – Deepanshu Sharma Oct 19 '11 at 11:25
It should be port 5900 rather than 5800, that might be catching you out. – Nicholas Smith Oct 19 '11 at 11:36
Sorry for being so late but port 5900 is already open on mac and assigned to vnc but still the connection is not possible. When i am trying to connect mac using ip-address:5900 then IE browser displays RFB 003.889 written on top. Apeart from that it shows nothing. Please help me as this is a major blocker in my project. – Deepanshu Sharma Oct 27 '11 at 11:55
Firewall is disabled on mac 10.6 and it is allowing all incoming connection but the problem still persist. – Deepanshu Sharma Oct 31 '11 at 6:29
How are you trying to connect? Essentially from a Windows machine you need a vnc client pointed at the ip address. If you're doing it from outside the network the Mac is on you'll need an ip address for the network or a dynamic domain name. – Nicholas Smith Oct 31 '11 at 7:54
