I wanted to contribute something back to the forums since I am always asking so many questions. I was able to find the answer on my own after I searched the forums/site without finding anything.
I was looking to change the Welcome message on the login page which said "Welcome to Softerra Adaxes 2011.1". I was able to find the localization file which is under
C:\Program Files\Softerra\Adaxes 3\Web Interface\Admin\App_GlobalResources\Strings.resx
This file has all the associated data for language settings. The setting I was looking for was
<data name="WelcomeTemplate" xml:space="preserve">
<value>Welcome to XYZ Company's Self Service Portal</value>
Hope this helps some one in the future!
