After deploying software updates to a collection the following State ID appears on the report titled: “States 1 – Enforcement States for a deployment”
State ID – 3010006 – “Failed to install update(s)”
When reading the WUAHandler.log file of a machine contained within this report, the following entries are found:
Async searching of updates using WUAgent started.
Async searching completed.
OnSearchComplete – Failed to end search job. Error = 0xc8000438.
Scan failed with error = 0xc8000438.
When noting the time stamps on the first two lines from the above entries, the times are generally seconds apart.
I have found that this is usually an indication of a corrupt or outdated Windows Update Agent. Installing the new agent, followed by an update scan or application will usually solve the issue.
