Subdomain pointing to another server

[cancer10]

Hi

First of all I am sorry if I am posting this in the wrong section, mods pls move it to the right section if so.


I have a domain name say www.abc.com hosted on a server say "Server1"

I have created a subdomain for that domain say http://chat.abc.com

Now, what I want is, I want to host chat.abc.com to another server say "Server2", which means chat.abc.com should point to another Server2 instead of Server1.

Please tell me the steps to do this (changing DNS records etc).


I will be highly greateful to you. Please?


Thank you so much in advance.
