After a few hours the DA Servers stop responding, and in the SMC the icon for the DAServer shows a red triangle.

Wonderware DA Servers, just like all Wonderware software, require a license to be installed. If a license is not installed, the DAServer will still run, but will default to running as a demo. Demo mode typically lasts for a few hours, after which time the DAServer will stop responding until the DAServer is restarted, or the computer is rebooted.
The icon on the DAServer can be used to determine the license status:
|Icon indicates that a license is correctly installed, and the DA Server is running normally.|
Icon indicates that a license is not found, and the DAServer is currently running in demo mode.
|Icon indicates that the license is not found, and the demo mode has expired.|
To fix this, a valid Wonderware license must be installed.
For DAServers released before 2012, this will typically be licensed through a wwsuite.lic file.
For DAServers released after 2012, this will typically be licensed through an archestra.lic file.
Note also that DAServer licensing may be bundled with other software components such as InTouch Runtime "With IO" licenses, Development Licenses, Historian Server licenses, System Platform bundles etc.
Confirmation of Success
See ICONS above after installing the proper license file and restarting the DAServer in the SMC.
