Windows Services
The Avid Workgroup VSS service is automatically started at system startup and should be
running all the time. This service always runs under the local system account. The Avid
Workgroup VSS service requires that the Windows Volume Shadow Copy service is also
running. The Windows Volume Shadow Copy service is installed by default and started
automatically.

The Avid Workgroup VSS service must run on the same machine as the Avid Interplay
Engine Server.
The Avid Workgroup VSS service requires that the Windows Volume Shadow Copy service
is also running.
Avid Workgroup Engine Monitor Service
The Avid Workgroup Engine Monitor is responsible for creating the Engine Server process and
for monitoring the health of the Engine Server process, the Apache HTTP server, and the
TCP/COM Bridge. On Failover Cluster installations this service is controlled by a cluster
resource of the same name.
The Avid Workgroup Engine Monitor regularly tries to connect to the Engine Server process, the
Apache HTTP server, and the TCP/COM Bridge. If those components are too slow to respond or
do not respond at all, the Engine Monitor will trigger restarts of those components through the
corresponding cluster resources.
The Avid Workgroup Engine Monitor logs actions and health issues to the Application Event
log.
