Checking if a computer is in the the Active Directory global catalog

Question

Hi,I need a script that can tell me if a computer is found in the Active Directory global catalog. The code below is returning inaccurate results. Every computer that failed the Try statement can be found in Active Directory when I search manually. Does anyone see the problem with this example?Import-Module ActiveDirectory
$server = "myserver.com:3268"

#Get the list of computers to test
$computers = Get-Content -Path "$PSScriptRoot\computers.txt"

#Check active directory for each computer
foreach($computer in $computers) {

try{
        $test = Get-ADComputer $computer -Server $server

if($null -ne $test) {
            Write-Host "$computer in AD" -ForegroundColor Green
        }
    }

catch [Microsoft.ActiveDirectory.Management.ADIdentityNotFoundException] {
        Write-Host "$computer not in AD" -ForegroundColor Red
    }
}Thank you!Rob

I added some bogus computer names to computers.txt along with some known computers and it seems to be working now. Let me know if this solution doesn't seem correct.&nbsp;Import-Module ActiveDirectory
$server = "myserver.com:3268"

#Get the list of computers to test
$computers = Get-Content -Path "$PSScriptRoot\computers.txt"

#Check active directory for each computer
foreach($computer in $computers) {

$test = Get-ADComputer -Filter 'Name -eq $computer' -Server $server

if($null -ne $test) {
        Write-Host "$computer in AD" -ForegroundColor Green
    } else {
        Write-Host "$computer not in AD" -ForegroundColor Red
    }

}&nbsp;
