so please tell me if u have any answer to this problem in .net 2.0 and iis server

For the first part of your question, this is not possible. You cannot control where a browser will send "xyz" There are many factors including a person's ISP that would determine where the request for "xyz" would be sent.

For the second part of your question, I would suggest setting up a redirect in IIS to forward all requests form xyz.com to www.xyz.com See http://technet.microsoft.com/en-us/library/cc732969%28WS.10%29.aspx for info on how to do that.
