503 Error comes from HTTP.SYS so you cannot change it from IIS.

If you are stopping the application pool during update of your ASP.NET website, best way would be to add a file called App_Offline.htm in the root folder with whatever you want to show users when application is offline.

ASP.NET runtime would redirect requests to this file if it's found in the website folder. So once you are done, you can just rename this file.

This link also might help since it's related. http://weblogs.asp.net/scottgu/archive/2006/04/09/442332.aspx

Unfortunately, you can't change the HTTP 503 Error page displayed when the AppPool is stopped.

The following errors are not customizable: 400, 403.9, 411, 414, 500, 500.11, 500.14, 500.15, 501, 503, and 505.
