Error: External exception C0000006
The External Exception C0000006 error generally occurs when a workstation loses its connection to the server while DBA Manufacturing is running.
The interruption may be very brief and may not be noticeable when using other applications. However, DBA requires a continuous connection to the server. If that connection is interrupted, the current DBA session may no longer be usable.
Local Area Network (LAN)
If this error occurs on a workstation connected to the server through a wired local area network, troubleshoot the network connection between the workstation and the server.
Possible causes include:
A faulty or intermittent network cable
A network switch or other network hardware problem
A problem with the workstation's Network Interface Card (NIC)
A problem with the server's NIC
A problem with the network cable connecting the server to the switch
Antivirus, firewall, or security software that is inspecting, delaying, or interrupting network traffic
If the error is occurring on multiple workstations, focus troubleshooting on shared network components such as the server's network connection, network switch, cabling, or security software.
If a workstation has both wired and wireless network adapters enabled, we also recommend disabling the wireless adapter while troubleshooting so the workstation uses only its wired network connection.
Wireless Connections
DBA Manufacturing should not be run directly across a wireless network connection.
Wireless connections are more susceptible to brief interruptions and changes in connectivity. Even a short interruption can cause the workstation to lose its active connection to DBA on the server.
If a user must work from a wireless computer, we recommend using Microsoft Remote Desktop to connect to a computer or server located on the wired network and running DBA within that Remote Desktop session.
What to Do After the Error Occurs
After receiving the C0000006 External Exception error, do not continue working in the current DBA session.
Close DBA Manufacturing and log back into the program.
If DBA cannot be closed normally:
Press Ctrl + Alt + Delete.
Open Windows Task Manager.
Locate DBA Manufacturing in the running applications or processes.
Select it and choose End Task.
Restart DBA Manufacturing and log back in.
If the error continues to occur, troubleshoot the network connection before continuing regular use of DBA.
For wired workstations, review the network components described above. For wireless workstations, move DBA access to a wired connection or use Microsoft Remote Desktop.
Restarting the affected workstation may also be helpful. If multiple users have lost their connection to DBA or the server connection has been disrupted, restarting the server may also be necessary.
