How to edit Smart404.aspx page

Jun 25, 2008 at 1:34 PM
I am trying to update the page not found message that is on the SMART404.aspx page with a more detailed message, but everytime I try and open it in Sharepoint Designer it crashes.
Is there another method I need to use to update this file?

The page is not a "page" as such.
You cannot edit it, it is merely hosted in sharepoint.
The whole idea is to update it in Vstudio and redeploy.

I made a "different" version for our company, wherein we host the aspx pages under /_layouts/Redirect.
_Layouts files are not stored in the sharepoint db by default. So you can play with them on the file system, but future updates to your WSP (solution) will of course destroy manually made changes.
