• Test File service and Test share paths both test as valid in Configuration Manager Manage Raw Data Files

ENVIRONMENT

• Empower 3 Enterprise or Workgroup

CAUSE

Windows update patches may require the computer to be rebooted after they are applied. LAC/Es do not have monitors to notify that a reboot is necessary.

FIX or WORKAROUND

Remote into the LAC/E to see if a reboot is necessary, or remotely reboot on a regular basis after scheduled updates. If this does not work, roll back the patches and reboot. 

ADDITIONAL INFORMATION

These same errors may happen if the LAC/E is installed and not added into the appropriate domain computer user group with proper permissions for the Watersservice built-in local Windows System account to write to the raw data share.
