I hate to say this, but its working now. Without making any configuration changes, I uninstalled Otter via the Inedo hub, rebooted the server, then reinstalled Otter. I was then able to add an agentless server without issue.

I'm obviously happy that it's now working, but I'm sorry for making you look into this.

Thanks.

Hello Rich,

Otter is running on Windows Server 2019, and I installed it via the Inedo Hub.

Thanks

Hi Steve,

Thanks for the response. I'm running Windows Server 2019. Following your suggestion about RSAT, I installed every available RSAT, but had the same issue. After installation, I restarted the the Otter and web services, but the problem remained, so I rebooted the server, but still see the error.

I've done some manual testing in PowerShell, and found that Test-WSMan, Enter-PSSession, and Invoke-Command all work without issue.

I'm attempting to add a server to Otter via WMI, instead of the Inedo agent, but I'm running into an issue. Otter administration is showing this error:
Error scanning PowerShell agent: Could not load file or assembly 'Microsoft.Management.Infrastructure, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. The system cannot find the file specified.

Is there something I'm missing?
