Scenario
Have you ever changed the name of a computer, removed that computer from WSUS, then struggled to get the renamed computer to reappear in WSUS?
Here are a few commands that will help you get things working quickly.
Solution
- From the client PC, enter the following at the command prompt to force the PC to register with the WSUS server:
wuauclt /r /reportnow
- The client PC should now show up in WSUS, either under Unassigned Computers, or another computer group if you have used client-side targeting.
- Once the renamed client PC is in the correct computer group – with approved updates ready to install – you can force it to detect the updates by running this command:
wuauclt /detectnow
- If the client PC is not appearing automatically in the right computer group – via client-side targeting – try this:
wuauclt /resetauthorization /detectnow
