greetings, I read that in order to customize 404 error messages on IIS, I should follow these steps : 1.Create a file that contains your custom error message, and place it in a directory. 2.In the Internet Information Services snap-in, select the Web site, virtual directory, directory, or file you would like to customize HTTP errors, and then click Properties. 3.Select Custom Errors. 4.Select the HTTP error that you would like to change, in this case 404. 5.Click Edit Properties. 6.Select URL from the drop-down list. 7.Type the URL, that points to your customized error message by entering the path to the URL beginning with the virtual directory name. If the file is present on the root of your Web site, you don't need to enter a virtual directory name. 8.Click OK. I need to know if the 404 error code will still be returned to search engines after this ? Regards, Thomas
