EXE/Script Advanced PowerShell get-content problem

Did you already try to upgrade to a newer PowerShell version as required?

This is what I get when I check the version, whether it be the 32 or 64 bits version:

PS C:\Users\Administrator> $PSVersionTable

Name                           Value
----                           -----
PSVersion                      3.0
WSManStackVersion              3.0
SerializationVersion           1.1.0.1
CLRVersion                     4.0.30319.36366
BuildVersion                   6.2.9200.17065
PSCompatibleVersions           {1.0, 2.0, 3.0}
PSRemotingProtocolVersion      2.2

So I think it is above the minimum required version, is there other thing else I should check for?

Thanks in advance.

Could you post the entire script please?

Hi, thanks for the reply, sure, here is it, please consider my comments in the first post, where I've mention that I have already tried changing the line $admpass = get-content "C:\passlib\admpass.txt" | convertto-securestring for $admpass = get-content "C$\passlib\admpass.txt" | convertto-securestring

I get different messages back, but none of them worked. Thanks in advance.

Import-Module 'C:\Program Files\Common Files\Skype for Business Server 2015\Modules\SkypeForBusiness'

$user1 = "usr4@domain.com"
$pass1 = get-content "C:\passlib\usr4pass.txt" | convertto-securestring
$cred1 = new-object -typename System.Management.Automation.PSCredential -argumentlist $user1, $pass1

$adm = "adm@domain.com"
$admpass = get-content "C:\passlib\admpass.txt" | convertto-securestring
$admcred = new-object -typename System.Management.Automation.PSCredential -argumentlist $adm, $admpass

$result="<prtg>`r`n"
$testcs = Invoke-Command -ComputerName remote1.domain.com -Credential $admcred -Argumentlist $cred1 -ScriptBlock {Import-Module SkypeForBusiness; Test-CsClientAuth -TargetFqdn remote2.domain.com -UserSipAddress "sip:usr4@domain.com" -UserCredential $args[0]}
    if ($testcs.result -eq "Failure") {
        write-host "Unable authenticate user"
    }
    else{
		$result+="  <result>`r`n"
		$result+="    <channel>Auth Test</channel>`r`n"
		$result+="    <value>"+$testcs.result+"</value>`r`n"
		$result+="  </result>`r`n"
        }
$result+="</prtg>"
Write-host "Sending Result to output pipeline"
$result

Hold on, is the passlib folder actually located on the probe? Or the core? Because the notifications are actually executed on and via the remote probe host, not the core server.

We do not have any remote probe currently, the script and passlib folder are located on the core or main probe, in fact we have only one server running PRTG where all sensors are being deployed, I've tried placing the passlib folder in the remote invoked server also, result is the same. Where should I have to place the folder? Are there any other factors I must take into consideration?

Ah sorry, disregard that. Is it possible that the sensor is executed within a user context that has no access to the folder where the credential files are stored?

Can you please give me more details about the user context? Setting about the Security Context are set to Use Windows credentials of parent device, parent device's Windows credentials are from a domain user who is joined to the PRTG server's administrators group.

Complementing last question, I've set the sensor settings with the parent device's Windows credential, which are from a domain user that is joined to the PRTG Server Administrators group, credential has the right access, but I'm still getting the same result, can you give me more detail about the user context?

Sorry about the delay, Luis. I did some reading and you might want to try the following:

$pass = (get-content "\\<fqdn-of-your-prtg-server>\c$\passlib\admpass.txt" | convertto-securestring)

Thanks for replying, I'm sorry to say that it didn't work either, I've tried with the Server's IP also, the result is the same "Power Shell 2.0 or above Required" along with the aforementioned error message stating that the path couldn't be found, the part that confuses me, is why am I getting the message "PowerShell 2.0 required" if I'm sure that the version is above that? Is this a generic message? Which or where is the PowerShell executable PRTG is running to execute the script?

Thanks in advance.

The only other way that comes to my mind would be this one:

function Passwords([ValidateSet("Get","Set")][string]$action)
   $passFile = "C:\Program Files (x86)\PRTG Network Monitor\Notifications\EXE\adm.pass";
   $keyFile  = "C:\Program Files (x86)\PRTG Network Monitor\Notifications\EXE\adm.key";

   if($action -eq "set"){
        $Key = New-Object Byte[] 32
        [Security.Cryptography.RNGCryptoServiceProvider]::Create().GetBytes($Key)
        $Key | out-file $keyFile
        Read-Host "Enter Password for the $($Server) server" -AsSecureString |  ConvertFrom-SecureString -key $Key | Out-File $passFile
   }
   if($action -eq "get"){
       $Key = Get-Content $KeyFile
       $Credentials = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $servers.smtpUser, (Get-Content $passFile | ConvertTo-SecureString -Key $key)
       return $Credentials;
   }

Call the function once with Passwords -Set in order to create the password files and Passwords -Get when you need the corresponding credential object. Let me know if it worked out!
