  2. Select "Error Pages"
  3. Select "Edit Feature Settings"

In the Run dialog type "inetmgr" and press Enter/Click OK.

Step 2 - Select "Error Pages"

In IIS Manager, select your website from the left-hand panel, and then select "Error Pages":

In the right-hand panel, select "Edit Feature Settings":


Step 4 - Select "Detailed Errors"
