Microsoft has just released the following KB Article:
Clicking the Update button in the System Center 2012 Endpoint Protection client user interface fails with error 0x8024402c
Symptoms
Consider the following scenario:
- The System Center Configuration Manager Administrator manages all updates in the environment.
- Users have no access to the Windows Update website.
- The Configuration Manager Software Update Point is configured and synchronizing.
- The Automatic Deployment Rule for Definition Updates is configured and appears to deliver updates nightly with no problem.
In this scenario, when a new client is deployed and the local Administrator clicks the Update button in the System Center 2012 Endpoint Protection client user interface (SCEP UI), the search for updates eventually times out and the following error is displayed:
0x8024402c – System Center Endpoint Protection couldn’t install the definition updates because the proxy server or target server names can’t be resolved
Analysis of the C:\Windows\WindowsUpdate.log file also indicates that the SCEP client is attempting to access the Microsoft Update Website.
