Finding machines not compliant with a specific security bulletin

Finding machines not compliant with a specific security bulletin

Originally posted on TechNet.

I read Marc’s post about Compliance Reporting and it was similar to a problem I deal with in my job. Part of my job is to run Update Management on one of the domains consisting of around 12,000 managed computers at Microsoft using WSUS. We do this in order to validate WSUS (and similar products) in an environment with real users. Another group at Microsoft audits my compliance, and often request a list of non-compliant machines for specific security bulletins. I have adapted Marc’s SQL script to do just that.

I ran into one issue, Marc’s SQL script will blocks clients from scanning while it runs. Since the script can take a long time to execute on larger data sets, I decided to allow SQL to read dirty data and unblock my clients (SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED.).

I hope you find this useful.
