Per the request of Accenture Federal Services, enable a site-level preference which allows site administrators to author text which will display immediately in a banner in the Windchill browser. For example: "Daily Maintenance Window: 8-9am EST and 5-6pm EST. Notification will be sent for any additional downtime."
There is a capability for this out of the box but it requires modification of Windchill codebase files on the server (begin_custom.jspf and banner.txt) and a restart of Windchill. By adding this preference, site administrators would be able to set banner text without having access to the application server.
