Website powered by joomla, requires a members-only area. When someone clicks on the Members Area link, they should be directed to screen where they will be prompted for a username and password (there will be one username and password for all users).
Once the username and password are correctly entered, the user should be able to view the members only area. The content for the members only area still needs to be powered by joomla.
The site is hosted on an IIS server.
I can provide more details in the PMB.
