Overview

The article describes how to modify the displayed screen for an ISA 2006 server.

It is possible to change the logo displayed at the top of the login page. The page may look like this:

The image shown here at the top is in GIF format and is 500x115 pixels. On a 32-bit machine the picture can be found in "C:\Program Files\Microsoft ISA Server\CookieAuthTemplates\PINSafeOWA\HTML" - if the ISA server was installed to a non-standard location then this will not be the location. The file name of the logo is lgnTop.gif.

In order to update the picture for display you can simply substitute a new logo of exactly the same format and size then restart the ISA service to complete the installation of the new logo. This should then display the next time the page is accessed. The end result should look like this:

Troubleshooting

If the page is requested by a refresh it is possible that the browser is displaying a cached version of the site. Clearing the cache within your browser may fix this.

If the logo is not of the same format (GIF) or of the same size (500x115pixels) then it may fail to display correctly.

If the name of the new image differs in case to the original then it may fail to load correctly.

When swapping the images it is recommended that you rename the old picture file and add the extension ".old". This will allow you to easily revert the image should the need arise.
