Testing computer existence in AD

Posted by: | August 29, 2011 | No Comment |

Forum question wanted to take a list of computer names in a csv

Using the Quest cmdlets it becomes

Import-Csv computers2.csv |            
foreach {            
 $comp =  Get-QADComputer -Name $($_.Name)            
             
 if ($comp) {$location = $comp.DN}            
 else {$location = "Does NOT exist in AD"}            
             
 New-Object -TypeName Psobject -Property @{            
  Name = $_.Name            
  Location = $location            
 }            
            
} | Export-Csv complocs.csv -NoTypeInformation

 

Read the CSV and for each computer see if we can find it in AD.  I’m searching whole AD and assuming less than 1000 machines. Alter the search properties if these don’t match your needs. Put the name and distinguished name (DN) in an object and write to CSV

Its just as easy with the Microsoft cmdlets

Import-Csv computers2.csv |            
foreach {            
 $comp =  Get-ADComputer -LDAPFilter "(name=$($_.Name))"            
             
 if ($comp) {$location = $comp.DistinguishedName}            
 else {$location = "Does NOT exist in AD"}            
             
 New-Object -TypeName Psobject -Property @{            
  Name = $_.Name            
  Location = $location            
 }            
            
} | Export-Csv complocs2.csv -NoTypeInformation

Main difference is that we have to use an LDAP filter in Get-ADComputer. Also we pick up the DistinguishedName not DN property

under: PowerShell and Active Directory
