PowerShell execute multiple task on different servers

If you find yourself feeling overwhelmed by the maintenance of hundreds or multiple servers, there is no need for concern; PowerShell can assist you, provided that you have a clear understanding of the required actions.

Below is a PowerShell code snippet that can shut down a server, restart a server, restart a service, or stop a service.

It is advisable not to attempt this in a production environment unless the necessary actions are permissible and the task has been approve.

An example image illustrating the output of the PowerShell script is included below.

Ensure to modify the server name or service name as appropriate. And most importantly, used an elevated PowerShell with Admin credentials.

Here's the PowerShell code:
$servers = @("Admin_server", "DB_Server", "Redis_Server", "Docker_server")
$action = @("Shutdown_server", "Restart_server", "Service_restart", "Service_stop")
$ix = 0

While ($ix -le 3) {

$server = $servers[$ix] # Get the current server name

$current_action = $action[$ix] # Get the action for the current iteration

Write-Host "Performing action: $current_action on server: $server"

switch ($current_action) {

"Shutdown_server" {Write-Host "Stop-Computer -ComputerName $server" `n}
"Restart_server" {Write-Host "Restart-Computer -ComputerName $server" `n}
"Service_restart" {Write-Host "Restart-Service -ComputerName $server -Name Redis" `n}
"Service_stop" {Write-Host "Stop-Service -ComputerName $server -Name *docker*" `n}

}
$ix++
}

#remove the Write-Host to push the action and change server name, service name accordingly

By removing the write-host statement, example: Stop-Computer -ComputerName $server ← this command will shutdown the specified server, if credentials are good and no other issues on the environment. Use the code sparingly.







Be still, be calm don't despair. We don't have all the answers. Lift up everything to God. He knows exactly what to do.
Pray and don't worry.

Print error 016-799 - Fuji Film Xerox

016-799 Fuji Xerox or Fuji Film print error code. That shows a description error as “Print instruction Fail detected in decomposer.” The error code and error description are alien languages for users and even system administrators who are not familiar with Fuji Xerox error code. The error code is quite simple and easy to fix, if the job print goes to the printer but print out doesn’t come out. So, basically the print job was received by the printer, but the printer just doesn’t know what type of paper or what size to use or which tray to utilize for the print out. In some instances, this is just a paper mismatch but the error description; if using Windows 10 to print does not exactly points to what is the issue. First thing to check, is the paper size selected by the user to print. Example, if the printer configuration is A3 and A4 sizes only. But then the person printing the file accidentally chooses “A4 Cover” then this error 016-799 will occur. ...
