IdleSessionLimitMin can only be set by GPO

Hi @pokepoke81, I think the problem here is that it is already set by group policy in your environment and that's what the error warns about. So if you would remove the group policy it would actually be able to apply the setting. Can you test that?

I am able to run the Powershell command Set-RDSessionCollectionConfiguration manually with all of the settings (including IdleSessionLimitMin) without getting an error. The error comes when trying from DSC (through ansible). I just tried re-running the DSC after manually applying the settings and I get a different error: "Failed to invoke DSC Set method: Unable to configure the RD Session Host server WC-RDS-SH03.wcdom.loc. Invalid parameter " that I'll have to look into why that's occuring.

It looks like I had another setting misconfigured and instead of complaining about that, it gave me this erroneous error about IdleSessionLimitMin. I was using the numbers for EncryptionLevel instead of the string. This documentation was confusing: https://docs.microsoft.com/en-us/powershell/module/remotedesktop/set-rdsessioncollectionconfiguration?view=win10-ps
