SYMPTOMS
You receive the following error messages when you try to use Microsoft Baseline Security Analyzer (MBSA) 2.0 to scan for a security update. The specific error message depends on whether you scan a local computer or a remote computer.

When you scan a local computer for a security update, you may receive the following error message:

An error occurred while scanning for security updates. (0x8024402c)

Note The 0x8024402C error code typically indicates that there is a proxy problem. However, no proxy server is being used.

When you scan a remote computer for a security update, you may receive the following error message:

Windows Update Agent is not installed. Ensure the local computer has been scanned with default settings or install the agent manually.

Note You may receive this error message even though the Microsoft Windows Update Agent is installed, and the computer is restarted.



CAUSE
This problem occurs when Group Policy settings for your computer are configured to use a Windows Server Update Services (WSUS) server to download updates. Additionally, this problem occurs when an MBSA 2.0 scan uses the default Group Policy settings.

By default, if Group Policy settings are configured to use a WSUS server, an MBSA scan tries to connect to the WSUS server to retrieve security update information. If the WSUS server is offline or otherwise unavailable, MBSA determines that it cannot connect to the WSUS server because of a proxy problem.



RESOLUTION
To resolve this problem, configure MBSA to scan Microsoft Update only. MBSA then ignores the WSUS policy setting and connects to Microsoft Update. To do this, follow these steps:
 * 1) Click Start, click All Programs, and then click Microsoft Baseline Security Analyzer.
 * 2) Click Scan a computer.
 * 3) Click to select the Advanced Services Update Options check box, and then click Scan using Microsoft Update only.
 * 4) Click Start scan.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.
