Unable to rename computer with powershell

$script = { Rename-Computer -ComputerName "ADMINIS-ID1PS7V" -NewName "SERVER1" }
$computerName = "ADMINIS-ID1PS7V"
$username = "Administrator"
$pw = "123!@#qaZ"

# Create Credentials
$securepw = ConvertTo-SecureString $pw -asplaintext -force
$cred = new-object -typename System.Management.Automation.PSCredential -argument $username, $securepw

# Create and use session
$session = New-PSSession -credential $cred -ComputerName $computerName
Invoke-Command -Session $session -ScriptBlock $script
Remove-PSSession $session

• I disabled the firewall on the machine.
• I ran enable-PSRemoting -force
• I even set the GPO with Allow remote server management through WinRM to enabled with *

I keep getting:
