While loop hangs in my script

Question

Hi guys,
I want to check if SCCM (install windows image) is ready.
If it's not, than it has to sleep. I want this in a while loop because when it takes longer, it must loop another
5 minutes.
When the image is ready it must go back to the rest of this script.
My loop hangs and the script never finishes. What am i doing wrong?
Kind regards,
André
$compObject = get-wmiobject -query "select * from SMS_R_SYSTEM WHERE Name='$hostName'" -computername "dhgms401" -namespace "ROOT\SMS\site_S01"
$compObjectstatus = $compObject.client
do {
Start-Sleep -Seconds 300
while ($compObjectstatus -eq 0)
write "Sccm is klaar "
Write "$hostName has been started"
$newHostName = Get-ADComputer -filter {(name -eq $hostName)}

Not 100% sure but, I believe the issue is with your conditional statement for your while loop
while ($compObjectstatus -eq 0)
$compObjectStatus will never change so your while loop will never equal 0 unless it did from the begining. You will have to requery each time to get an update on the status, so possibly create a function on the query end of things, and just run the function
Function GetStatus
$compObject = get-wmiobject -query "select * from SMS_R_SYSTEM WHERE Name='$hostName'" -computername "dhgms401" -namespace "ROOT\SMS\site_S01"
$compObjectstatus = $compObject.client return $compObjectstatus
do {
Start-Sleep -Seconds 300
while (GetStatus -eq 0)
write "Sccm is klaar "
Write "$hostName has been started"
$newHostName = Get-ADComputer -filter {(name -eq $hostName)}
I cannot test so I do not know if it works as expected
