What are the services and ports required to run MBSA?
A. The required services are listed under the System Requirements section of the Readme.html file (installed with MBSA) and in the MBSA Help file (linked to in the left hand pane of MBSA user interface). These requirements include Remote Registry service, Server service, File and Printer Sharing service, and Automatic Updates service. The wsusscan.cab file is downloaded from the Microsoft Web site over HTTP based on your Internet Explorer settings. Remote computer scans are performed by using TCP ports 135, 139 and 445. In a multi-domain environment where a firewall or filtering router separates the two networks, TCP ports 135, 139 and 445 and UDP ports 137 and 138 must be open in order for MBSA to connect and authenticate to the remote computer being scanned. In addition you may need to configure the Windows Update Agent for a static RPC port allocation setting and allow this as an exception through the Windows Firewall as well.
