Windows Updates and Relay Flow

Usage and Config Platform
1

Hi All,
Can someone help me with the flow of traffic when deploying Windows updates to Win 7 machines?
The fixlet tells it to download an update from windowsupdate website, but does it actually do this or does it use the normal flow where the relay has the file cached and the pc just get it from there?

Unless the fixlet uses a “download now” actionscript command, the file is always delivered through the server/relay architecture. The Server uses the HTTP link provided in the fixlet to download the file and the infrastructure delivers it.

thanks for the super quick reply. This is what I see in log on the wind 7 machine:

sha1:8ff7cfc3a121bf705c52c19403b5626148eafffd,

then lists the msu and sha1 value and http://download.windows… as the URL

So in reality it still is really getting the files from its relay, correct?

Yes. The prefetch line is parsed in different ways by different components. The client merely asks for the value from its relay. The server is the one actually performing the download for all the clients and passing the file through the relays.
