Finding a Specific Setting in your Client Settings

With ConfigMgr 1806, the Application Catalog service and site roles are no longer needed, so for me it was a good opportunity to have 2 less servers to care and feed for. But because I was a dummy, in Default Client Settings I had selected my app catalog site explicitly rather than letting the client automatically pick (I have no idea why I did this). And when you make a new client setting, it inherits the settings of the default, so anyone who made a custom policy with Computer Agent had that setting. This setting being defined prevents the removal of the application catalog roles.

I have 41 Client Settings, I’m not about to look through each of them for Computer Agent settings. So Powershell to the rescue. Get-CMClientSetting will get you a list of all your Client Settings, but there won’t be any information on them. There’s a -Setting which will return all the settings of the specified type, but as it turns out, nothing to tell you which Client Setting contains that setting. So it turns out, you have to get every Client Setting, and interrogate it if it has the Computer Agent setting. With this code I was able to find the five Settings that had Computer Agent specified, and change the Default Application Catalog website point.

$allsettings = Get-CMClientSetting | select -ExpandProperty Name
foreach ($name in $allsettings) {
    if (Get-CMClientSetting -Setting ComputerAgent -Name $name) {
        write-host $name
    }
}

I could have gone farther with this, as the object returned will have a PortalURL property, but merely listing the Settings that had Computer Agent was sufficient for this. This could be generalized to look for any Client Setting with a particular setting, and further to look for specific values if needed.
