Which machine are you trying to connect from your ubuntu computer? I guess you are trying to connect to a remote ubuntu computer. If so then you need to enable remote view from your system system that you are trying to connect to. Do this :
Navigate to the System>Preferences>Remote Desktop. There you will see a window that has this two check boxes:

• Allow other users to view your desktop
• Allow other users to control your desktop

Tick both the boxes and you are ready to go...

I know this is the setting for a ubuntu machine if i need to view it from a remote location. But here the case is different, i need to connect to the remote machine which Windows XP installed. I enabled "Allow users to connect remotely to this computer" option which i get by right-clicking on my computer>properties. But still i cannot get through.... Please help... I don't know what have i missed...

Oops! Mate thats not gonna work, Windows used RDP protocol for remote connection but to connect through ubuntu or any other linux, you need a protocol that is supported by Linux, so you need to install VNCServer on Windows XP machine to get this connection going.
