问题
I'm writing a powershell v2 script that I'd like to run against a remote server. When I run it, I get the error :
Connecting to remote server failed with the following error message : The WinRM client cannot process the request. Unencrypted traffic is currently disabled in the client configuration. Change the client configurati on and try the request again. For more information, see the about_ Remote_Troubleshooting Help topic.
I looked at the online help for about _ Remote_Troubleshooting, but it didn't point me towards how to enable unecrypted traffic. Below is the script that I'm using that is causing me problems.
Note: I have already run Enable-PSRemoting on the remote machine to allow it to accept incoming requests.
I have tried to use a session option variable, but it doesn't seem to make any difference.
$key = "HKLM:\SOFTWARE\Microsoft\PowerShell\1\ShellIds"
Set-ItemProperty $key ConsolePrompting True
$tvar = "password"
$password = ConvertTo-SecureString -string $tvar -asPlainText –force
$username="domain\username"
$mySessionOption = New-PSSessionOption -NoEncryption
$credential = New-Object System.Management.Automation.PSCredential($username,$password)
invoke-command -filepath C:\scripts\RemoteScript.ps1 -sessionoption $mySessionOption -authentication digest -credential $credential -computername RemoteServer
How do I enable unencrypted traffic?
回答1:
AllowEncrypted is defined on the client end, via the WSMAN: drive. You must be running powershell.exe (or powershell_ise.exe) as an elevated process.
ps> cd WSMan:\localhost\Client
ps> dir
Name Value
---- -----
NetworkDelayms 5000
URLPrefix wsman
AllowUnencrypted false
Auth
DefaultPorts
TrustedHosts
You would change it like so (after changing to the directory above):
ps> set-item .\allowunencrypted $true
Hope this helps,

You probably will need to set the AllowUnencrypted config setting in both the Client and the Service. The Service setting has to be changed in the remote server using the following:
set-item -force WSMan:\localhost\Service\AllowUnencrypted $true
And don't forget to also enable Digest Authorization:
set-item -force WSMan:\localhost\Service\Auth\Digest $true

This worked for me:
enable-wsmancredssp –role server
