Mounting and Unmounting NTDS.dit file

Question

Hi,
I am creating a PowerShell script that will give a possibility to mount the NTDS.dit file from the backup and compare the Backup AD with the current AD. If you are interested I can share the unfinished script. The problem is that I want to moun the NTDS.dit
file in a scripted maner. When you mount the file manualy using:
dsamain -dbpath "<path_to_the_NTDS.dit_file>" -ldapPort 10389
the process starts normaly but to end it the user needs to press "Ctrl+C" and once the process is running the script will not conitnue. I want to stop ager certain amount of time. I tried different ways starting the command as different process
(e.g.
cls
$w1 = ""
$w2 = ""
get-process -name powershell -ErrorAction SilentlyContinue | Foreach-object {$w1 = @();$w1 += $_.ID}
start-process powershell.exe -argument '-nologo -noprofile -executionpolicy bypass -command "dsamain -dbpath "<path_to_the_NTDS.dit_file> -ldapport 33389"'
Start-Sleep -Seconds 10
get-process -name powershell | Foreach-object {$w2 = @();$w2 += $_.ID}
$e = Compare-Object -ReferenceObject $w1 -DifferenceObject $w2
$e1 = foreach ($r in $e) {if($r -like "*=>*"){ $r }}
$e1 | Foreach-object {$y = @();$y += $_.InputObject}
Start-Sleep -Seconds 600
stop-process -id $y
and
Start-Process "Powershell.exe" -WindowStyle Hidden -ArgumentList "
  Start-Job -Name 'Mounting the NTDS.dit' -ScriptBlock {
    Do
        # --- This will mount the ntds.dit file from the backup ---
        dsamain -dbpath $NTDS_File -ldapPort $LDAP_PortNumber
    Until ($False)
    }; Start-Sleep -s $time_ntds
But both commands don't allways work. I was browsing other solutions and came accross the main article of
dsamain:
Active Directory Domain Services Database Mounting Tool (Snapshot Viewer or Snapshot Browser) Step-by-Step Guide
and little bit from top of the "Steps for using the Active Directory databse mounting tool" there is a line that says:
"..You can stop Dsamain by pressing CTRL+C in the Command Prompt window or, if you are running the command remotely, by setting the
stopservice attribute on the rootDSE object. "
Can anyone tell me how to use stopservice, e.g. give example scripts or equivelent.
Or if anyone has any other ideas how to acomplish the task I would be more than happy to hear them out and try.

Solved it by using this command:
                      $time_ntds = 10
                      $time_ntds = $time_ntds*60                  
                      Start-Process "Powershell.exe" -WindowStyle Hidden -ArgumentList "
                        Start-Job -Name 'Mounting the NTDS.dit' -ScriptBlock {
                          Do
                                # --- This will mount the ntds.dit file from the backup ---
                                dsamain -dbpath $NTDS_File -ldapPort $LDAP_PortNumber
                          Until ($False)
                        }; Start-Sleep -s $time_ntds
                    start-sleep -Seconds 35
