Use maintenance windows for servers to ensure the updates happen only when they should вЂ“ (more on this in a future blog).

Leverage custom collections that are just for patching вЂ“ this will be helpful when reporting on compliance.

And note the recommended limit is 1000 updates so most environments will not hit this limit in a single year

#Sccm patch deployment best practices update#

Use a single Software Update Deployment for each year вЂ“ this means that all the updates for workstations and servers are downloaded to the same deployment.

Automatic Updates/Deployment should only be done if a non-production вЂњPilotвЂќ deployment can be first to validate the given updates.

Products should be configured at the SUP level to only what is needed вЂ“ in general only the Operating Systems that are deployed and supported in the environment and the products that are deployed.

Classifications should be configured at the SUP level to only what is needed for the given environment вЂ“ in general the following Classifications: вЂњCritical Updates, Definition Updates (if SCEP is deployed), and Security UpdatesвЂќ.

iVision SCCM Best PracticesД«efore we leave the topic for today, I should mention a few вЂњBest PracticesвЂќ that we at iVision recommend: So it becomes clear that the Rube Goldberg analogy is not too far off.

The Installation Deadline is derived from the Software Available time so Thursday at 10pm plus 56 hours = Monday at 6am. In the above example the Evaluation runs on patch Tuesday at 10pm and the Available time is adding to that time (Tuesday at 10pm plus 2 days = Thursday at 10pm). The deployment scheduleвЂ™s вЂњSoftware Available TimeвЂќ is based on the time the Evaluation runs.

The above filter is set to download any update that has at least 1 client that requires the update and is NOT superseded. The Evaluation Schedule is when the SUP will run the rule and download the updates that meets the filters. Some explanation for the scheduling is required.

Create a new Software Update Group each time the ADR runs.

Deployment Schedule вЂ“ Based on Client Local Time.

Deployment Schedule вЂ“ Software Available time = Specific Time:2 Days, Installation Deadline = 56 hours.

Software Updates filters вЂ“ Required вЂњ>0вЂќ and Superseded вЂњNoвЂќ.

Evaluation Schedule вЂ“ custom scheduled to run Monthly, every 2 nd Tuesday at 10pm (patches are released 18:00 UTC).

With those requirements the ADR should look like: All patches must be installed to all systems by the following Monday at 6am. An SCCM exampleДЇor example: LetвЂ™s assume are tasked with patching workstations and are to be deployed no earlier than Thursday at 8pm following вЂњPatch TuesdayвЂќ. The trick with ADRs is to configure the schedule to run at appropriate timeвЂ¦and then set the deployment schedule to follow based on the desired timing. New to SCCM 2012, ADRs are SCCMвЂ™s answer to WSUSвЂ™s вЂњautomatic approvalвЂќ. With the server/client schedule working like a well-timed clock, the next ball in our Rube Goldberg update machine, is Automatic Deployment Rules (ADRs). The client scans the SUP database for all the available updates and any required updates are then reported back to the SUP.

The server sync and the client scan work together to get the full picture of what updates are needed. The synchronization schedule should be the same or more frequent as the clients Software Updates scans configure within the SCCM вЂњClient SettingsвЂќ. The SUP should be set to download only the patches that meet the Classification and Products that are supported in the given environment. The top of SCCMвЂ™s patching infrastructure is the Software Update Point (the SUP). To start, we must have a solid understanding of the overall process flow of how SCCM imports, prepares, deploys and monitors software updates (how all the dominos are laid out). With the release System Center Configuration Manager 2012 R2 the patching process has become easier, but itвЂ™s not an вЂњEasy Button.вЂќ Care and preparation must be done to ensure that software patches are deployed successfully to the desired targets at the desired time. ThereвЂ™s a bit more detail in the process but you can get the idea that every domino in the process must line up correctly or the cool trick of patching will not work properly. Then, the server will create a new list of updates to push, the updates are sent to Deployment Points and a new Update Deployment is scheduled to run.

A server downloads all the updates from Microsoft and the clients scan the server for new updates that are required. You might not be familiar with a Rube Goldberg machine, a complex machine that is built of chain reactions: a ball rolls, then hits a lever, the lever sets off another reaction and so on.Дeploying software updates to the enterprise is not unlike one of these crazy cool machines.
