use of local WSUS server?

[stevew]

I noticed theres an option to specify a WSUS server. I did this but it still seems to be downloading from Microsoft.

Our WSUS server is up to date and works for Windows server 2012R2 servers so its a known good configuration.

Is there anything I need to change on the WSUS server to allow wsus offline updates to use it?

Thanks

There are two known issues with local WSUS servers:

1. Only dynamic download links, which are extracted from the WSUS catalog file wsusscn2.cab, can be redirected to a local WSUS server.
   
   Static download links are still downloaded from the Microsoft download sites. This includes the catalog file wsusscn2.cab itself and all other download links from the static download files in the wsusoffline/static directory.
   
   You could add an option

   Code: Select all

   wsusonly=Enabled

   to the [Miscellaneous] section of the file UpdateGenerator.ini, but this affects dynamic download links only.
   
   See: viewtopic.php?f=3&t=3973
   
   
2. The bundled download utility wget doesn't support encryption, so you can't use a https URL for your WSUS server.
   
   You could replace the bundled wget with the latest Windows builds from https://eternallybored.org/misc/wget/ , which support encryption.

Some files (such as wsusscn2.cab) aren't provided by WSUS. They are required for wsusou to work and will be downloaded from MS.
