Используя WSManConnectionInfo и Runspace, я смог получить нужные детали.
WSManConnectionInfo connInfo = new WSManConnectionInfo(new Uri("http://ServerName:5985/wsman"));
Collection<PSObject> output = null;
string command = "Get-DnsServerForwarder";
using (Runspace remoteRS = RunspaceFactory.CreateRunspace(connInfo))
{
remoteRS.Open();
using (var pShell = PowerShell.Create())
{
pShell.Commands.AddCommand(command);
output = pShell.Invoke();
}
}
