Microsoft Baseline Security Analyzer

The Microsoft Baseline Security Analyzer (MBSA) can scan Microsoft Windows NT for security issues and missing security patches.

If you don’t have access to Microsoft when checking for missing security patches download and place in the folder where MBSA was installed. Even if the is installed the MBSA will still try to contact Microsoft, but the scan will still work if the contact should fail because of a firewall.

Note if using antivirus that scans archives, then one might want to exclude, as it might introduce slow performance.

Note in Win2k if not having installed “Client for Microsoft Networks” for the Network Adapter (Don’t need to be bound), then the MBSA will report at critical problem about “Computer not found.”
