Forefront definitions not updating wsus

The binary delta definition file is generally 1-15MB in size and is used if your client is more than a month behind in its definition updates.The delta definition file is generally 1-15MB in size (usually smaller than the binary delta definition file) and it installed typically on a daily basis (released 3 times a day).

In order to find the machines to target with these updates, we need to make some DCM rules.

These DCM rules will allow us to populate collections dynamically based on the dates of their definition files.
