thank you for explanation!! Makes sense.

I am still getting the error though (:
PS C:\Windows\system32> C:\scripts\Set-ADMSserviceLogonAccountServersv2.ps1
Server server01,server02 cannot be reached


I can ping servers. Tried using FQDN and still the same error.

Also, I want to update more than one service account. I see you added Foreach loop for the server. Can you pls tell me how to do the same for more than one service account.

foreach ($server in $serverN){
if ((Test-Connection -ComputerName $Server -Count 1 -Quiet) )
{
