Avid Interplay Engine Servers and Services

Avid Workgroup TCP/COM Bridge Service
The Avid Workgroup TCP/COM Bridge service acts as bridge to the Avid Interplay Engine
Server.
The Avid Workgroup HTTP Server needs the Avid Interplay TCP/COM Bridge to connect to the
Avid Interplay Engine Server.
Connectivity
The Avid Workgroup TCP/COM Bridge listens to port 8318.
Processes
The process running is usually NXNTCP~1.exe from NXNTCPCOMBridge.exe.
Windows Services
The service “Avid Workgroup TCP COM Bridge” is automatically started at system startup and
should be running all the time.
Requirements
The Avid Workgroup Server Browser must run on the same machine as the Avid Interplay
Engine Server.
The Avid Workgroup TCP/COM bridge needs to run under the same user account as the
Avid Interplay Engine Server. To check under which user the bridge runs, use the Windows
Services Control Panel.
To check the user account, click Start, click Run, and type services.msc. Right-click Avid
Workgroup TCP COM Bridge and select Properties. In the Log On tab, the This Account
option should display the Server Execution User.
c
Use the tool NXNServerUser.exe to change the Server Execution User. Do not change the
settings in the Control Panel. See “Troubleshooting the Server Execution User Account” on
page 229.
Avid Workgroup VSS Service
The Avid Workgroup VSS service provides backup functionality to the Avid Interplay Engine
(Interplay version 2.1 and later only). By working with the Windows Vol u m e S h a d ow C o p y
service, it significantly reduces the impact of the backup process on other engine operations.
The Avid Interplay Engine needs the Avid Workgroup VSS Service to create scheduled backups
of its databases.
