I am have a really hard time getting this to work. Hopefully someone can help me out!

I am currently working on a Powershell deployment script for a service. After installing the service, I'd like to set the Service Recovery options to "Restart the Service" every time the service crashes after 0 minutes.

Does anyone know how to do this using Powershell to set these options for remote machine?

You can write a powershell function using sc.exe as explained here. The function will look something like:

function Set-Recovery{
    param
    (
        [string] 
        [Parameter(Mandatory=$true)]
        $ServiceName,

        [string]
        [Parameter(Mandatory=$true)]
        $Server
    )

    sc.exe "\\$Server" failure $ServiceName reset= 0 actions= restart/0 #Restart after 0 ms
}

And you can call the function like:

Set-Recovery -ServiceName "ServiceName" -Server "ServerName"

Note: The account you are running the script must have admin rights on the remote server.

Please, simplify..

Use the oldiest sc.exe in powershell code. Is more easy and fully functional.

sc.exe failure "ServiceName" actions= restart/180000/restart/180000/reboot/180000 reset= 86400;

The restarts, in milliseconds. And the last reset, in seconds.

(Each restart in 3 min, and the reset in 1 day)

Bye!

I've taken @Mohammad Nadeem idea and expanded it with full support of all actions instead of just primary one. I've also used Display Name for service rather than service name so it's a bit easier to provide parameter. 

function Set-Recovery{
    param
    (
        [string] [Parameter(Mandatory=$true)] $ServiceDisplayName,
        [string] [Parameter(Mandatory=$true)] $Server,
        [string] $action1 = "restart",
        [int] $time1 =  30000, # in miliseconds
        [string] $action2 = "restart",
        [int] $time2 =  30000, # in miliseconds
        [string] $actionLast = "restart",
        [int] $timeLast = 30000, # in miliseconds
        [int] $resetCounter = 4000 # in seconds
    )
    $serverPath = "\\" + $server
    $services = Get-CimInstance -ClassName 'Win32_Service' | Where-Object {$_.DisplayName -imatch $ServiceDisplayName}
    $action = $action1+"/"+$time1+"/"+$action2+"/"+$time2+"/"+$actionLast+"/"+$timeLast

    foreach ($service in $services){
        # https://technet.microsoft.com/en-us/library/cc742019.aspx
        $output = sc.exe $serverPath failure $($service.Name) actions= $action reset= $resetCounter
    }
}

Set-Recovery -ServiceDisplayName "Pulseway" -Server "MAIL1"

I've created a blog post about it: https://evotec.xyz/set-service-recovery-options-powershell/. I've not tested this in other scenarios than restart of service. Probably would need some work to support all scenarios.

If it were a local service you could use sc.exe however you want to change settings for remote service. One way to do this is to set the registry keys directly using remote registry:

Here are the settings you'll need:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<ServiceShortName>    
Value Name                Data Type    Description
FailureActions            REG_BINARY   Configuration information for 1st, 2nd, and subsequent failures.

What I would do is setup the service recovery options the way you want them and then read the registry value FailureActions

$actions = get-itemproperty hklm:\system\currentcontrolset\services\<ServiceShortName> | select -Expand FailureActions

Then serialize this to disk for use later:

$actions | Export-Clixml C:\actions.xml

When your ready to remotely configure the service, re-read the FailureActions data, connect to the remote registry and set the registry key:

$actions2 | Import-Clixml C:\actions.xml
$key = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey([Microsoft.Win32.RegistryHive]::LocalMachine, "<RemoteComputerName>")
$key2 = $key.OpenSubKey('SYSTEM\CurrentControlSet\Services\<ServiceShortName>', $true)
$key2.SetValue('FailureActions', ([byte[]] $actions))

The Carbon library has a pretty comprehensive Install-Service cmdlet which lets you specify recovery actions, e.g. (adapted from the Install-Service doc page):

Install-Service -Name DeathStar -Path C:\ALongTimeAgo\InAGalaxyFarFarAway\DeathStar.exe -OnFirstFailure Restart -RestartDelay 10000

This will install the DeathStar service and restart with a 10 second delay after the first failure.

jborean93 has created a custom type that exposes the native C# service objects and methods to PowerShell. The included Get-ServiceRecovery and Set-ServiceRecovery functions make it easy to view and change service recovery settings within PowerShell. https://gist.github.com/jborean93/889288b56087a2c5def7fa49b6a8a0ad

.\ServiceRecovery.ps1
Get-ServiceRecovery -ComputerName 'MyComputer' -Name 'MyService'
Set-ServiceRecovery -ComputerName 'MyComputer' -Name 'MyService' -Actions @('RunCommand', 'Restart', 'None') -Command '"C:\Windows\System32\cmd.exe" /c echo hi'

For the DSC fans out there, looks like this functionality is also being worked into xPSDesiredStateConfiguration (xService) at some point in the future. https://github.com/dsccommunity/xPSDesiredStateConfiguration/pull/679
