Autonomous System: An AS number is used with routing protocols (like EIGRP and OSPF), all routers that share information with each other in a group are members of the same AS number, (an AS number can be 1-65535).Asynchronous Transfer Mode: Used to move computer data, video, or audio over a network.

Patch Manager will work with standalone WSUS environments, or with SCCM environments that have a software update point (SUP).

Alternatively, if you happen to have both of these environments, Patch Manager can be used effectively in both to quickly and easily deploy patches.

They were only applied to machines that experienced issues.

Patch Manager has allowed us to consistently push patches out and ensure a stable and secure environment.”“In the past, we were not easily able to deploy 3rd-party patches to clients.

To obtain updates from Microsoft Update, the WSUS server uses port 8530 for HTTP protocol and port 443 for HTTPS protocol. If your organization does not allow those ports and protocols open to all addresses, you can restrict access to only the following domains so that WSUS and Automatic Updates to communicate with Microsoft Update: The firewall configuration steps above are intended for a corporate firewall positioned between WSUS and the Internet.

Because WSUS initiates all its network traffic, there is no need to configure Windows Firewall on the WSUS server.Ensure you are downloading only the updates your network needs.If you had a setting selected before but turned it off at a later date (such as ‘All Languages’ instead of just ‘English’), they will still be present in the WSUSContent folder – there is no automatic deletion process.Today I had an interesting issue where a particular server’s WSUSContent folder increased in size incredibly quickly to the point where the logical disk it was hosted on ran out of space. There is a handy utility, WSUSUtil.exe, which allows IT administrators to reset the WSUS components and rechecks each update in the database, verifying the content is present in the WSUSContent folder and downloads it again if necessary from Microsoft.Although this allows you to set a clean slate for WSUS, there must be a reason why your WSUSContent folder increased in size so quickly in the first place.Although the connection between Microsoft Update and WSUS requires ports 80 and 443 to be open, you can configure multiple WSUS servers to synchronize with a custom port.
