Overview
A known issue with a Lexmark Fax Printer driver can cause System Five on Cloud to crash around 10 seconds after signing into the environment. This Cloud Remote Desktop session will continue to crash after 5 to 30 seconds after reconnecting.
Symptom: This started occurring after a new printer was installed along with a new fax printer driver installation.
Root Cause: Lexmark DLL LMFX1N4Z.DLL
Detection: This is caused by the Lexmark dll which is LMFX1N4Z.DLL. This is a printer fax driver which gets installed after installing the driver. To confirm the cause:
- Open the Windows Event viewer.
- Browse through recent Application events and look for an "Application Error" or "Application Crashing" event.
- Check the crashing error is from the remote application msrdc.exe
- The error will explain the faulting module causing the crash on the event log. In this case it was the LMFX1N4Z.DLL
Resolution - Replace or Delete
- Check the printer list and look for a Lexmark Fax printer.
- If this fax printer is required, contact your IT team to replace the crashing printer driver.
- If the Lexmark Fax Printer is not required. Delete the printer.
- Once driver is removed, sign back into System Five on Cloud and monitor for 60 seconds. The remote desktop session should no longer be crashing and disconnecting.
