Hi Neo,
What I'm saying is, is that getting your own property page to display in ADUC is pretty advanced stuff. I would not claim to have done this myself. You will need to be versed in either C++ or VB and COM programming.
If you want to look into it:

Or if you have a Server 2008 / Vista or Win 7 box, the version of ADUC which runs on these includes and attribute editor tab which enabled you to view all attributes in a list (it's basically the same as the attribute editor in ADSIEDIT).
If you havent raised your domain functional level to 2008 you have to make a few changes to the configuration naming context to make the tab visible in ADUC.
