Getting started with Microsoft Windows Server Update Services 3.0, Part 6: Disconnected network (1)

In case that you have WSUS server separated from the Internet, you can’t get updates directly. Microsoft has provided a solution by setting up another WSUS server which can connect and update from the Internet. Next, download updates from the Internet to this server and then export updates and metadata to files and copy (may be via backup tape) to the WSUS server which is on the disconnected network.

To implement this solution, you need to perform 3 steps:

  1. Matching Advanced Options.
    Make sure that on the advanced synchronization options for the express installation files features and languages on the exported server match the settings on the imported server.
  2. Export files and metadata from the exported server.
    Export files will be done by using ntbackup command and metadata which is description and detail of updates will be export by using wsusutil.exe.
  3. Import files and metadata to the imported server.
    Import files and metadata will be use the same process as when export.

In the following example, I’ll configure to enable express installation files features so that both server required to enable this feature and the langauge is only English. Since this topic is quite long, it will separate into 2 posts. In this post, I’ll show only first 2 steps.

Note: You required local Administrative privilege on both WSUS server to perform this. The wsusutil.exe tool can only be run on a 32-bit platform.

  13. Next, I’m going to backup metadata. Open command-line to C:\Program Files\Update Services\Tools. type “wsusutil export export.cab export.log”.
    Note: This command will be exported metadata to a file called ‘export.cab’ and also create a log file called ‘export.log’ which for debugging.
