PowerShell script failure on remote execution

powershell

On executing a PowerShell Remote Script I am getting an error like following

Invoke-Command : Exception calling "ToXmlString" with "1" argument(s):
"The requested operation cannot be completed. The computer must be
trusted for delegation and the current user account must be configured
to allow delegation.

The exact line of code the execution is breaking is as follows:

$rsa = New-Object System.Security.Cryptography.RSACryptoServiceProvider
$key = $rsa.ToXmlString($true)

Can anybody help me to resolve this?

You need to enable credential delegation, so that PowerShell can pass your username/password to the remote computer, so that it can use them to perform the operation which is failing. See this answer on StackOverflow for instructions/details.

Powershell Remote Execution Error on EC2

The server and client do not need to be in the same domain, however, the error message you are getting seems to me to indicate not an authentication error, just a basic networking error. Are there firewalls between you and the WinRM server that may be preventing this communication? Can you telnet to port 5985 on the WinRM server? 5985 is the HTTP port that WinRM uses in 2008 R2.

edit: Also note that you're going to need to add the WinRM server to the TrustedHosts list on your client, but I don't think you've gotten to that point yet.
