Thanks... as you noted, that wasn't exactly what I am needing, but I did try those options and they don't appear to work.  Based on other posts here, others have had the same experience - that the Discover page shows regardless of whether Don't Show is checked or not.

 - make sure that 'Don't set value' is un-checked for the Discover page option.

 - policy settings are processed at certain times by default ... run the following server console command to have them processed immediately:  

         tell adminp process new

 - in the Notes client, close the Discover page and then close any open clients (Notes, Admin, Designer)

 - restart Notes.

 - authenticate with home/mail server (Ctrl - F5 or just open the on-server Mail file)

 - restart Notes again

That should do it

Thanks for the response, but I'm getting inconsistent results with this setting.  It seems that the "Home" page gets set to the "Discover" page.  (Clicking Home from the Open List opens Discover instead of the Home page from Bookmark.nsf.) On one PC (with the Client/Admin/Designer), I was able to open Bookmark.nsf, bookmark it, and then select to set it as the Home Page.  But, this morning, it starting opening the Discover page again.  On another PC with the standard Client, I select to set Bookmark.nsf as the Home Page, but the setting doesn't take affect at all.

I think I will accept this as a bug and hope that no user really wants to stop the Discover page from opening!
