Wsus not updating all clients
As an administrator, you have the option to approve or block specific updates.
You can also specify the date on which the software will be distributed.
The utility will automatically check for updates, hotfixes, and patches to Microsoft software and then distribute them to all the computers on the network.
This free utility from Solar Winds enhances WSUS and is a step between bare WSUS capabilities and full patch management.
If you only have a small network and can’t really justify the cost of a full patch management facility, this tool could be your best option.
So, a good place to start when checking on problems is to ensure that the flow through of WSUS is getting to each agent on the endpoint machines.
With this tool, you can start off by making sure that each WSUS agent is actually operating and that the central WSUS server can communicate with each of them.
The Solar Winds Diagnostic Tool for the WSUS Agent monitors the client status of WSUS agents running on the endpoints on your network.
