Working on site this week with a client who has a 512kb link back to their headoffice. I deployed a new server which had WSUS configured to replicate content and approvals from a central server in headoffice. The problem was however that it tried to download 23GB of updates from the server during working hours and the bandwidth to headoffice became very limited. Now I know WSUS is supposed to use background bandwidth, but it just didn’t seem to work.
I needed to find a way to stop WSUS downloading updates from the other server without permanently crippling the server. The answer ended up being very simple.
- In the WSUS 3.0 console, expand the tree and find the Options node.
- Select the Update Source and Proxy Server option and enter in a dummy server name and port number as you can see below. Once this is done, restart the WSUS Administration website in the IIS Management console and the downloads will stop.
Later you can easily revert this change and continue the downloads without any issue.
