Issue
Continuum running under MS Windows 7, Vista or MS Windows Server 2008 (including R2)
Access event viewers at workstations other than the primary access server do not show events.
Alarms acknowledged at one CyberStation would remain unacknowledged in the other CyberStations.
Product Line
Andover Continuum
Environment
- CyberStation
- Microsoft Windows 7
- Microsoft Windows Server 2008
- Microsoft Windows Server 2008 R2
Cause
Problem in Microsoft MSMQ component.
MSMQ service might not send or receive messages after you restart a computer that is running Windows 7, Windows Server 2008 R2, Windows Vista or Windows Server 2008.
This will cause any Continuum component that uses MSMQ (such as Alarms and Access Events) to fail.
Microsoft has issued a hot fix for this MSMQ problem.
Resolution
Use the following command prompt test to verify the problem
netstat -ano | findstr 1801
The command tests whether MSMQ is listening for messages.
For example, Continuum WS 'A' is the primary access server (PAS) with an Event Viewer 'EV' up, a second Continuum WS 'B' is also displaying the same EV.
If MSMQ is functioning normally you should see the following.
1. is the IP address of WS 'B' that has established a link to WS 'A'
2. is the IP address of WS 'A', the PAS in this case.
2560 is the listening MSMQ process PID
You can clearly see that there is a MSMQ process (2560) in WS 'B' LISTENING on port 1801
If there is no MSMQ process listening the output of the command will show the loopback or localhost IP address 127.0.0.1
and you have to install the following Microsoft hotfix:

** In very rare occasions, removing MSMQ and adding MSMQ again to the PC is required.
** Once it is re-installed, please refer to Access event viewers running in a workstation other than the Primary Access Server stop displaying e... to set the MSMQ CleanupInterval setting to one hour in the primary access server.
