If you work with Windows Server Update Services you know that it is a bit of a black box. Fortunately Microsoft has made some easy command line options available.
There are so many things you can do to confirm the WSUS is happy and here are a few.
1: WSUS Utility to Check WSUS Health:
Run this command and then check the EventViewer to see if WSUS thinks it is happy or sad.
"C:\Program Files\Update Services\Tools\WsusUtil.exe" checkhealth
2: Surf To The WSUS Apps:
If you want to make sure that WSUS is up, connectivity (firewalls, routes and IIS are good) just open a browser and surf to:
http://server.domain.local:8530/selfupdate/iuident.cab
In case you are wondering where that URL came from, it is what WSUS clients, like Windows 10 PC’s and other servers use to make their connections. You can easily figure this out by looking at IIS on your WSUS server.
3: How to Easily Reset WSUS:
Run this command and then check the EventViewer to see if WSUS thinks it is happy or sad.
"C:\Program Files\Update Services\Tools\WsusUtil.exe" reset
As you can see in the screen shot above the WSUSUTIL utility has many switches which Microsoft explains HERE:
| Command | What it enables you to do | When you might use it |
|---|---|---|
| export | The first of the two parts that make up the export / import process. The export command enables you to export update metadata to an export package file. You cannot use this parameter to export update files, update approvals, or server settings. |
|
| import | The second of the two parts that make up the export/import process. The import command imports update metadata to a server from an export package file created on another WSUS server. This synchronizes the destination WSUS server without using a network connection. |
|
| migratesus | This command migrates update approvals from a SUS 1.0 server to a WSUS server. |
|
| movecontent | Changes the file system location where the WSUS server stores update files, and optionally copies any update files from the old location to the new location |
|
| reset | Checks that every update metadata row in the database has corresponding update files stored in the file system. If update files are missing or have been corrupted, WSUS downloads the update files again. |
|
| deleteunneededrevisions | Purges the update metadata for unnecessary update revisions from the database. |
|
| listinactiveapprovals | Returns a list of update titles with approvals that are in a permanently inactive state because of a change in server language settings. |
|
| removeinactiveapprovals | Removes approvals for updates that are in a permanently inactive state because of a change in WSUS server language settings. |
