I'm trying to test if winrm works on a list of systems; however, I can't seem to catch/silence the error that appears when I attempt to connect to a system. It appears to work on one system:
PS C:\Users\Egr> winrm id -r:system1
IdentifyResponse
ProtocolVersion = http://schemas.dmtf.org/wbem/wsman/1/wsman.xsd
ProductVendor = Microsoft Corporation
ProductVersion = OS: x.x.xxxx SP: x.x Stack: x.x
But doesn't work on another:
PS C:\Users\Egr> winrm id -r:system2
WSManFault
Message = WinRM cannot process the request. The following error occured while using Kerberos authentication: The net
work path was not found.
Possible causes are:
-The user name or password specified are invalid.
-Kerberos is used when no authentication method and no user name are specified.
-Kerberos accepts domain user names, but not local user names.
-The Service Principal Name (SPN) for the remote computer name and port does not exist.
-The client and remote computers are in different domains and there is no trust between the two domains.
After checking for the above issues, try the following:
-Check the Event Viewer for events related to authentication.
-Change the authentication method; add the destination computer to the WinRM TrustedHosts configuration setting or use
HTTPS transport.
Note that computers in the TrustedHosts list might not be authenticated.
-For more information about WinRM configuration, run the following command: winrm help config.
Error number: -2147024843 0x80070035
The network path was not found.
I've tried surrounding it in a try/catch block, but it doesn't seem to silence it. I am attempting to run a check against these systems to determine which ones have WinRM configured correctly and working; but if the script keeps outputting this text, it won't work very neatly. Is there any way to suppress this text, or is there a better way to test WinRM connectivity?
You could redirect the error stream to $null
and evaluate $LastExitCode
to detect an error:
$rhost = 'system2'
winrm id -r:$rhost 2>$null
if ($LastExitCode -eq 0) {
Write-Host "$rhost OK" -ForegroundColor green
} else {
Write-Host "$rhost unavailable" -ForegroundColor red
}
