I also prefer to run locally or remotely Microsoft Baseline Security
Analyzer with the latest catalog file from
http://go.microsoft.com/fwlink/?LinkId=76054 using the following
options (that I got from MS Exchange blog):
mbsacli.exe /nd /nai /nvc /wi /catalog <path>\wsusscn2.cab /listfile
<path>\servers.txt
/nd: To avoid any download from the Internet
/nai: To avoid WUA updates on the workstation that run MBSA, but
also on remote servers.
/nvc: To avoid check for new version of MBSA
/wi: Permit to display all updates, even ones rejected by the WSUS
server. Particularly useful for Exchange admin not allowed binding
against SUS server.
/catalog:<path>\wsusscn2.cab
/listfile <path>\servers.txt : The servers.txt file contains
NetBIOS name or FQDN name list in column of all servers to be scanned.
This can find a whole bunch of patch related issues + the use of
restricted browsing etc on remote hosts.
