Client Visibility Issues: Fix WSUS Clients appear then disappear in the console

WSUS client issues

In the corporate realm, the WSUS Update Services Console plays a pivotal role. Formerly recognized as Software Update Services (SUS). This Microsoft-developed program empowers administrators to efficiently oversee update distribution and hotfix deployment for Microsoft products across networked computers. For more articles I have written, see the following hyperlinks: Configuring WSUS Email Notification to Work With Office365, How to setup and configure Windows server update services (WSUS), Important Areas to Master on WSUS (Installed and not applicable, Install 1/4, and Installed / Not applicable 100).

Note: When I log in to each workstation and type in the CLI(CMD) the following command below. I am able to see these machines from the WSUS console but the others disappear.

wuauclt.exe /detectnow /reportnow

Reason for unexpected behaviour

When encountering cloned servers, a common occurrence arises due to identical SUSClientID. Each interaction with WSUS Update Services Console overwrites the entry with fresh server data, causing the existing machine to vanish.

FAQ on WSUS Client Issues

What would the next step be after forcing WSUS clients to re-register with the server and fail?

First, to force WSUS clients to re-register with the server, we have mentioned the steps above. You will have to launch the Windows PC and open an elevated Command Prompt. Then you will have to run the command: wuauclt /resetauthorization /detectnow. This command resets the client’s authorization settings and initiates a detection cycle.
Secondly, after running the command. Wait for a few minutes, and then check the WSUS console to see if the client reappears. If the client still doesn’t appear. Ensure that the Group Policy settings are correctly configured, and investigate network or firewall issues.

Can WSUS client issues be attributed to WSUS server issues?

Yes, WSUS client issues can sometimes be related to problems on the WSUS server. Examples of these are database corruption issues, out-of-sync servers, and inadequate Server Resources.
