Powershell - size limit error

Hi EE

SubSun helped me with the script below that compares members of two groups . It works great on small groups but if they are over a certain amount which I dont know .. I get the error below .. the groups I am trying to compare have 20k users .

Any ideas what I need to modify ?

Function Compare-Member ($Source,$Group) {
      $DN = (Get-AdGroup $Source).DistinguishedName
      "Working on group $Group"
      $result = Get-ADGroupMember $Group | % {
      If (!(Get-ADUser $_.SamAccountName -properties memberOf |
            ? {$_.memberOf -Match $DN})){$_.SamAccountName}
      }
      If ($result){
      "Missing Members"
      $result
      }
      Else{
      "All NUIDs Match !"
      }
}

Compare-Member Test_1 TEST_4


ERROR below ..

PS E:\Projects\Groups> .\CompareABGroups.ps1
Working on group TEST_4
Get-ADGroupMember : The size limit for this request was exceeded

Try to replace Get-ADGroupMember $Group

With
Get-ADGroup $Group -Properties Members | Select-Object -ExpandProperty Members | Get-ADObject | ?{$_.ObjectClass -eq "user"}

Open in new window


Function Compare-Member ($Source,$Group) {
      $DN = (Get-AdGroup $Source).DistinguishedName
      "Working on group $Group"
      $result = Get-ADGroup $Group -Properties Members | 
		Select-Object -ExpandProperty Members | 
			Get-ADObject | 
				?{$_.ObjectClass -eq "user"} | % {
      If (!(Get-ADUser $_.SamAccountName -properties memberOf |
            ? {$_.memberOf -Match $DN})){$_.SamAccountName}
      }
      If ($result){
      "Missing Members"
      $result
      }
      Else{
      "All NUIDs Match !"
      }
}

Or try...
Function Compare-Member ($Source,$Group) {
      $DN = (Get-AdGroup $Source).DistinguishedName
      "Working on group $Group"
