Hi everyone
Sometime over the past week, I noticed my WSUSContent folder almost doubled in size (going from approximately 260gb up to 460gb).
After some research, I discovered that this increase was entirely due to the introduction of express installation files (.psf) now living in my WSUSContent.
The checkbox to download express installation files has never been ticked on this server. It is a well maintained server, we run the server cleanup wizard at the start of every month. We don't patch anything directly from this server, SCCM infrastructure feeds of it and we patch everything using that.
A Microsoft PFE advised me that if any of my downstream WSUS servers (I have 77 in total, 28 autonomous, 49 replica) do by chance have "express installation files" checked, then it will send that upstream and force my upstream server to pull down this content.
That is not ideal.
Unfortunately, majority of all the downstream servers exist in different networks/domains that I have no access to or control over. I don't know the people who support them, this is a large organization with many cooks in the kitchen.
My questions are, for anyone in the know..
1) Is this true? Is the upstream server at the mercy of such a choice made downstream?
2) Is there anything I can do on the upstream server to prevent this happening?
3) Is there anything I can do to determine which downstream server is triggering this action?
I considered routinely deleting any *.psf files from WSUSContent, but that seems impractical and does not actually fix the issue. I also considered declining all historic updates and just dealing with the content month by month (cumbersome).
Any useful advice would be greatly appreciated. Thanks
