I get this message in the health report:

Product / patch installation or server upgrade required
All required products must be installed on all servers in the farm, and all products should have the same patching and upgrade level across the farm.
Upgrade is required on server XXXB. Without the upgrade, the server is not in a supported state.

I have a farm with two frontends and a database server and compared everything, but can't find any differences. I really like to know the insights about how this rule works.

I looked at the versions of the SharePoint components and de versions of the software installed on the server.

Any help would be appreciated.

Thanks. Mark

Hiya,

Installation of an update was run on only one of the frontend servers. But no PSConfig was run. When running PSConfig on a server, it will check the different file versions and compare if all files are available on all servers in the farm

This can however also be a false negative, with a "files not installed, rebooting the farm and running the psconfig afterwards will fix this.

The patching is not committed to the farm until the PSConfig is run.

Run Get-SPProduct -Local. It will update the installed products in the Configuration database. See if that lets you proceed.

HI Mark,It sees that the patch is Installed but the PS config has not run on the server.Run the products and configuration wizard on the server which shows the error.

Hi All,

Yes Get-SPProduct -Local has worked for me.

Many Thanks.
