If you ever have experienced that after your vCenter server reboots – due to Windows updates, the “VMware VirtualCenter Server” service is not starting?
I have seen it a few times and every time it’s during a weekend 
So to make sure your vCenter service (or other) is always running you could use this powershell script to check if a service is running, and if not start it.
To make sure you know if the service wasn’t started after a reboot or other cause, I have added a mail function to the script 
function FuncCheckService{
param($ServiceName)
$arrService = Get-Service -Name $ServiceName
if ($arrService.Status -ne "Running"){
Start-Service $ServiceName
FuncMail -To "to-email@domain.com" -From "from-mail@domain.com" -Subject "Servername : ($ServiceName) service started." -Body "Service $ServiceName started" -smtpServer "relay.mailserver.com"
}
}
function FuncMail {
#param($strTo, $strFrom, $strSubject, $strBody, $smtpServer)
param($To, $From, $Subject, $Body, $smtpServer)
$msg = new-object Net.Mail.MailMessage
$smtp = new-object Net.Mail.SmtpClient($smtpServer)
$msg.From = $From
$msg.To.Add($To)
$msg.Subject = $Subject
$msg.IsBodyHtml = 1
$msg.Body = $Body
$smtp.Send($msg)
}
FuncCheckService -ServiceName "VMware VirtualCenter Server"
Create a PS1 file and schedule it to run every 15 or 30 minutes.
It works great and is simple….
