I have a script that changes network settings on a remote computer, but it fails if there's not local admin rights on the system. It's pointing to over 100 computers on the network. Instead of failing I'd like it to come back with a notification that the account doesn't have admin rights on the computer.

$filename = "C:\temp\computers.txt"

$computers = get-content $filename

foreach ($comp in $computers)
{
    If ( ([Security.Principal.WindowsPrincipal] [Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator"))
    {
        $NICs = Get-WmiObject -Class Win32_NetworkAdapterConfiguration -ComputerName $comp -Filter "IPEnabled=TRUE"
        foreach($NIC in $NICs) 
        {
            $DNSServers = "10.19.4.70","10.19.4.109"
            $null = $NIC.SetDNSServerSearchOrder($DNSServers)
            $null = $NIC.SetDynamicDNSRegistration("TRUE")
            $null = $NIC.SetWINSServer("10.1.4.116","10.16.5.204)")
        }
    }
    ELSE 
    {
       Write-Host "Not an admin on" $comp
    }
} 

The script above uses a common script for testing for admin rights, but it doesn't appear to work with domain accounts. Any help or advice would be appreciated.

Thank you

Thank you for your prompt response. Then why do I get a false when I'm an administrator?

PS C:\windows\system32> ([Security.Principal.WindowsPrincipal] [Security.Princip
al.WindowsIdentity]::GetCurrent()).IsInRole(`
>>
>>         [Security.Principal.WindowsBuiltInRole] "Administrator")
>>
False

Are you an administrator on the local machine and running elevated?

Not what I asked.  Are you running as a member of the "local administrators" group and running elevated?

At the same prompt type: WHOAMI /PRIV - post what is listed.

YOur permissions look correct.  I can run the in a domain or on a standalone and it has never had an issue.  Perhaps you should try restating your system and see if it works:

Use these lines:

$p=[Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()
$p.IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator)
