I am able to connect to the VNC server on local host the problem is that I am not able to connect to server remotly. – Ravi shankar Dec 26 '09 at 6:53
how 'remote' is 'remote'? intranet? need to traverse routers (nat)? – akira Dec 26 '09 at 10:58

Can you tracert to the remote server successfully? If not, at was point does the trace stop? If you can, check the configuration on the server, as VNC can be configured to reject connections based on different requirements.

It might be time to check out pcap or wireshark, just to make sure that the connection is going out on the line. Perhaps running winpcap on the server (or tcpdump, if the server is UNIX) would help you isolation the problem to your host or to your server.
