Task servers require the Windows account and, if running email-related tasks, an Outlook application logged in and running at all times. Often task server failures are caused when the account has been logged off by a system restart. This means you need to manually log back into the associated Windows account then start the task servers manually.
Once logged back onto the correct account:
Navigate to \\servername\prodisk\proclaim\batch\tasksdesktopicon.
Right-click taskserver.exe then click Run as administrator.
Alternatively:
Open Task Scheduler.
Right-click on Start ATS.
Click Run.
If you are still having issues with your task servers, please raise a new case online and reference the title of this article.
