The UCServer service does not start automatically after the Windows server is booted.
The UCServer service cannot be started manually.
Start the UCServer as an application instead of as a service. To do this, start the "EUCSrv.exe" file in the UCServer installation directory.
However, this step is only possible if the UCServer is stopped as a service, i.e. it is not hanging in the startup process.
Starting the UCServer as an application serves to locate the cause of the problem. A window appears in order to see what the UCServer is doing during the startup process and at which point it gets stuck.
Please create a screenshot of this.
Close the server window again to allow the further procedure.
Please check first whether the UCServer service can be started manually. At the same time, please check on your Microsoft Windows Server what is selected as the startup behavior.
The UCServer service should start "automatically".
You can disable the dependencies for the UCServer. This means that log files are also written from the start of the server. If the server starts with deactivated services then normally a service is also responsible for the failure.
Other possible causes
If the UCServer service still fails to start, this is most likely due to the system environment.
Here we give you some guidance:
- The SQL database server is not accessible or not working correctly.
- The Microsoft Access database is corrupt or too slow, see Repairing the Access server database.
- Incompatibility 32-bit Access Database Engine on 64-bit Microsoft Windows systems.
- The Active Directory server is not accessible.
- There are too many files in the log files folder (C:\Program Files\estos\UCServer\logs), so Windows cannot create the new log files fast enough when UCServer starts.
- The local user administration is corrupted. ( => observed in connection with the UMReplicator).
- Telephony service is not started or reacts too slowly.
- The used TSP does not work correctly.
- Call recording has been set up, but the UCServer cannot find/open the CAPI DLL.
- This can be disabled in the general.xml file in the config directory under "<CallRecorder><Enabled>" by changing the value to "0.
It may also be possible to find out the cause of the error by starting the UCServer as an application instead of a service.
