Error message collected from the Windows Event viewer


Closing a TCP socket with local port number 50062 in process 6172 is taking longer than expected. The local port number may not be available until the close operation is completed. This happens typically due to misbehaving network drivers. Ensure latest updates are installed for Windows and any third-party networking software including NIC drivers, firewalls, or other security products. 


Troubleshooting steps

  • Force closed and reopened stuck apps using the task manager
  • Recreated outlook Profile
  • Checked TLS settings. 1.0, 1.1, 1.2, and 1.3 are enabled.
  • Reviewed application logs
  • Reviewed system logs and found an error pertaining to network drivers.
  • The error referenced an application PID number. this corresponds with the Express Network connection service
  • Reinstalled the ethernet and Wi-Fi drivers.
  • Reviewed firewall logs for blocks
  • Tested several documents. No issues
  • Followed up with the user, and the problem is intermittent.
