PowerShell can be used to write and query objects on swarm clusters using the InvokeWebRequest method and InvokeRestMethod.

PowerShell should be installed on all Windows Server distributions since Windows Server 2008 R2.

Head a domain

The basic command is below but as you can see the response is a little garbled.

Invoke-WebRequest -Uri http://tony.demo.sales.local -Credential csadmin -Method Head

Here’s how we get the raw content of the head. The main change is to put the actual web request in brackets and add the .RawContent property.
