Powershell Script - Export AD Group Membership containing large members

#Created By - Abhishek Bansal

<#Read Me !! 
1. Script Usage - Useful if members of AD Group are large in number. There are cases where Get-ADGroupMember fails when we have lots of members. ( More then 5K /6K )
2. Script is capable of exporting not only users objects but others too. ( Ex Groups ).
3. User need to input AD Group name when prompt & results can be checked in Groupname_Membership.csv file.

For using it, just copy the below code, run it
#>

$group = Read-Host "Enter AD Group Name"
$dn = Get-ADGroup -Identity $group -Properties * | Select objectClass -ExpandProperty Member

$line = 0 
$linecount = $dn.Count
$percentagecomplete= 0

foreach($row in $dn)
{
$line++
$percentagecomplete = ($line/$linecount)*100
$row = $row.trim()

Write-Progress -Activity "Checking Status.." -PercentComplete $percentagecomplete -Status "$line out of $linecount"

Get-ADObject -Properties * -Filter{DistinguishedName -like $row} | Select Name,Samaccountname,@{n="Member Category";e={$_.ObjectClass}} | Export-Csv ./$group.Membership.csv -NoTypeInformation -Append

}
