Getting error while trying to invoke a powershell command on a remote machine

Question

machineName have tried executing a script using invoke-command in the following way:

 Invoke-command -filepath C:\scripts\GettMembers.ps1 -computername "machinename" -credential $Getcredential 

But I am getting the following error :

Connecting to remote server failed with the following error message : The WinRM client cannot process the request because the server name cannot be resolved. For more information, see the about_Remote_Troubleshooting Help topic.

But I was able to add the machine to the trusted hosts of the local machine using the following command :

winrm set winrm/config/client `@{TrustedHosts="machineName"}' 

Solution 1

The problem appears to be that "machinename" isn't something your DNS knows how to resolve. This isn't a powershell problem, but rather a system configuration problem.

You can verify this by asking powershell to resolve the machine name with something like this:

$machine = "machinename"
[System.Net.Dns]::GetHostEntry($machine)

If you get an error, that means that you're using a machine name that can't be resolved (ie: windows can't convert "machinename" to an IP address). It's not a matter of trust or permissions, it's that your computer doesn't think "machinename" is a valid machine on your network.

Have you tried using a fully qualified address (eg: machinename.mycompany.com)?

Solution 2

I was getting this error on two servers that were configured for DNS and could ping the target. The resolution was this command:

netsh winhttp reset proxy

Although completely unlikely, this saved our problem after days of experimenting!
