We are having issues consistently patching using SCCM. We get around 90-95% of all workstations each month. The weird thing is it's not always the same machines. A bunch of machines don't get patched one month. The next month, without changing anything, it gets patches from the last month and the current month. What could be causing this inconsistency?

    Inconsistent patching behavior in SCCM can stem from various factors. Here are some common reasons for this issue and steps to address them:

    1. Network or Connectivity Issues: Intermittent network problems or connectivity issues can prevent machines from receiving updates. Check for network disruptions, firewall settings, or any configurations that might interfere with SCCM's communication with client machines.
    2. Client Health Issues: Sometimes, client machines may have issues communicating with SCCM. Check the SCCM client logs on affected machines (C:\Windows\CCM\Logs) for errors or issues and run client health checks to ensure they're properly configured.
    3. Recurring Maintenance Windows: If you have maintenance windows set up, ensure they aren’t conflicting or overlapping, preventing patches from being applied consistently.
    4. Disk Space and Resources: Check the disk space on client machines. Insufficient space can cause updates to fail.
    5. Troubleshooting with SCCM Logs: Utilize SCCM logs on both the server and client machines to identify specific errors or issues during update deployments.

    By systematically checking and addressing these potential causes, you can often identify and resolve the inconsistencies in SCCM patching. Remember to test changes in a controlled environment before deploying them broadly.
