How many computers can MBSA scan simultaneously?
Scanning in MBSA is not performed in parallel unless multiple copies of MBSA are run at the same time to scan different computers. Mbsacli.exe can be used with the new /listfile (list of computer names or IP addresses) parameter to scan computers listed in a text file containing computer names or IP addresses. This file can be a maximum of 100 MB in size. Using scripting (not provided with the MBSA download package) administrators can populate this text file from an Update Services server target group or from Active Directory.
