Hi, Andrew.

 

You're getting that error because using both -Session and -Credential on the same call to Invoke-Command is not a supported combination, which you can see from the documentation:

 

 

That said, this script is also unnecessarily complex, where you can simplify it down to the following:

 

# Prompt for credentials
$cred = Get-Credential;

# Use Invoke-Command to run the script block with elevated credentials
Invoke-Command -ComputerName $workstationName -Credential $cred -ScriptBlock {
    # PowerShell commands here
    Set-ItemProperty -Path 'HKLM:\System\CurrentControlSet\Control\Terminal Server'-name "fDenyTSConnections" -Value 0;
    Enable-NetFirewallRule -Name "FPS-ICMP4-ERQ-In-NoScope";    # Using the pre-defined name of the rule specific to the domain profile.
    Enable-NetFirewallRule -DisplayGroup "Remote Desktop", "Network Discovery", "windows management instrumentation (wmi)";
    Get-Process;
}

 

The only time you might look to create a separate session would be if you have a valid use case for calling Invoke-Command against the same workstation multiple times, but I can't recall seeing such a scenario.

 

Cheers,

Lain
