Software error while connecting to the scan server


Description of the Error

When attempting to load the EXScan software, encountering a failure to start the Scan Server can lead to a software crash, accompanied by specific error codes:

  • 0x00000012
  • 0x00000014 

These error codes directly pertain to the inability to initiate communication with the Scan Server due to the occupied port, leading to the software's initialization failure.

Verification Steps

To verify this issue, navigate to the following path within the software installation directory:


Check the logs for the following output, indicating failure to initialize the Scanner Server:

scanservice Process state changed! state: QProcess: :NotRunning


scanhub Process state changed! state: QProcess: :NotRunning

Identifying the cause

Another application or process currently occupies the communication port required by EXScan on your Windows system, thereby preventing successful connection establishment with the Scan Server.

To identify the conflicting task, follow these steps:

  1. Open the command prompt in Windows.
  2. Type in the following command:

netstat -aon|findstr "1883"

This command retrieves the Process ID (PID) of the task utilizing the occupied port.

Example outputs:

C:\Users\EinScanSupport> netstat -aon|findstr "1883"
TCP    [ : :1]:1883	[ : : ] : 0	LISTENING	6208
TCP    [ : :1]:1883	[ : : 1] :49702	ESTABLISHED	6208
TCP    [ : :1]:49702	[ : : 1] :1883	ESTABLISHED	6264

In this example, PID 6208 occupies port 1883.

C:\Users\EinScanSupport> netstat -aon|findstr "1883"
TCP	[ : :]:1883	[ : : ]:0	LISTENING	6520

In this example, PID 6520 occupies port 1883.

Resolution Steps

  1. Navigate to the Windows Task Manager.
  2. Enable the display of the PID column:
  3. Locate the process associated with the identified PID and terminate the ask.

EXScan should now run properly. If the issue persists, proceed as follows:

  • Right-click on the identified task, open its file location, and uninstall it from your system.

These steps should resolve the conflict allowing EXScan to function without issues.
