From time to time, the BITS queue might get clogged. This is usually the result of a corrupted download within the queue or another underlying issue. If this occurs, patching will not flow through Barracuda RMM. Support will, at times, advise clearing the BITS queue after the team has looked at the WSUSClientDiagnostic information. This article, in brief, will describe ways to reset the BITS queue.
If the BITS queue checks errors in the WSUSClientDiagnostic, it does include remediation steps from Microsoft's advisement on BitsAdmin commands. The following have a few options on how to reset the BITS queue.
Resetting BITS Queue and Windows Update Agent through Automation
- Remove the Patching Policy from the impacted Device (if it is OM managed and other devices are patching, only the impacted device should suffice)
- Download this script from GitHub and unzip it
- In Barracuda RMM go to Automation
- Select Library
- Click on New Script
- Name the script "Reset Windows Update"
- Browse for the unzipped Reset-WindowsUpdate.ps1 file
- Give the script a Category of your choosing then Save
- Now run the script
- Go to Automation
- Select Run Now
- Choose Item from Library
- Find Reset Windows Update
- Target the Device you wish to reset BITS Queue and Windows Update Agent
- Click on Run Now
- Allow for the script to complete and reboot the device
- After 60 Minutes, re-apply the Patching Police to the impacted Device
