+.SYNOPSIS
+    Use sc.exe to set the failure flag
+.DESCRIPTION
+    The FailureActionsOnNonCrashFailures feature of the service controller
+    cannnot be reliably managed in code via anything but sc.exe. Managing the
+    registry key value on its own has proved inadequate. This cmdlet gives us
+    an easily mockable and testable way to invoke sc to manage this flag.
+.EXAMPLE
+    PS C:\> Invoke-SCFailureFlag -ServiceName WSearch -Flag 1
+    This will invoke the equivelent of '& sc.exe failureFlag WSearch 1'
+#>
+function Invoke-SCFailureFlag {
+    [CmdletBinding()]
+    param (
+        [Parameter(Mandatory = $true)]
+        [System.String]
+        $ServiceName,
+        [Parameter(Mandatory = $true)]
+        [ValidateSet(0,1)]
+        [System.Int32]
+        $Flag
+    )
+
+    process {
+        & sc.exe @('failureFlag', $ServiceName, $Flag) | Out-Null
+        # A quick sanity check to make sure the value was set as expected without having to parse the string output of sc.
+        $failureFlag = (Get-ItemProperty -Path HKLM:\SYSTEM\CurrentControlSet\Services\$serviceName -Name 'FailureActionsOnNonCrashFailures').failureActionsOnNonCrashFailures
+        if ($failureFlag -ne $Flag) {
+            throw "sc.exe did not succesfully set the failure flag for $servicename"
+        }
