Windows Server Update Services (WSUS) is one of the most basic components of the Windows Server platforms.
It automatically downloads all the necessary updates from the official Microsoft update website and distributes them throughout your network of Windows computers.
Although WSUS is an excellent tool for patch and update management, it lacks some functionalities.
One of the biggest challenges of people managing WSUS servers is when the clients are not reporting or communicating back to the server.
Fortunately there are some alternatives or tools that can work together with the WSUS server to help diagnose and fix client problems.
In this article we’ll review some of those tools and software that can help you diagnose WSUS clients.
What is WSUS?
Windows Server Update Services (WSUS) helps IT managers manage and install the latest Microsoft updates and works as a server/client architecture.
WSUS is a Windows service and program that manages the distribution of updates released by Microsoft Update, for a computer network.
It automatically downloads these updates from the Microsoft website and then distributes them to all the computers.
The server manages and distributes all the updates such as hotfixes, service packs, device drivers, and feature packs for the clients.
It is a fundamental component of the Windows Server platforms.
Diagnosing WSUS Clients
In a perfect world, WSUS Server would have full connectivity with its clients all the time.
But this is rarely the case. For many reasons, some or all the WSUS client agents may not report back to the WSUS server, and there is nothing that WSUS can do here.
Many admins have to walk to every computer and start troubleshooting.
When this disconnection between WSUS clients and servers exists, you need third-party tools to help you diagnose the issues.
To fill some gaps left by WSUS, some people look for alternatives or tools that can use in conjunction.
Some of the most important diagnostics that you should consider running on failed WSUS clients are:
- Check the client’s state:
Verify the computer for admin rights, the Automatic Update services, and other related processes and services.
- Verify the Windows Automatic Updates (AU) configuration:
Check the AU configuration settings, such as proxy, state, etc.
- Check the connection to the server:
Test connectivity with the server and attempt to find the issue.
- Reporting and logging:
Client should save logs or create reports that might help in identifying the issue later.
- Find alternative ways to update:
In case the WSUS Server is unable to communicate with its clients, you can use alternative methods to keep all clients updated.
