An empty LabTech patching tab on an agent indicates that the Windows Update agent on the local machine is unable to provide LabTech with patch information. The UPDATES - Empty Patch Window internal monitor should detect this issue on an agent and run the autofix script Monitor Empty Patch Window, in an attempt to resolve the issue. If the autofix script is unable to fix the issue, a ticket will be created and manual troubleshooting steps will be needed.
In this case, the Windows Update agent on the local machine or a local network (firewall) is preventing the machine from accessing Microsoft's Windows Update site. If all agents for a client are unable to send patch information to LabTech verify all agents have access to the following sites and make any necessary firewall adjustments to allow these below sites:
- https://*.update.microsoft.com
- https://*.update.microsoft.com
- https://download.windowsupdate.com
If an individual agent has an empty patching tab, it indicates an issue with the Windows Update agent on the local machine. To attempt to resolve the issue, run the Microsoft Fix-It Tool for Windows Update on the agent which can be downloaded at the below link:
