如何使用 PowerShell 在 IIS 中设置 RapidFailProtectionInterval？

Question

I'm trying to configure the Application Pool of WsusPool, on a MS WSUS setup, to raise the Failure Rapid-Fail Protection Interval from 5 minutes to 30 minutes as an administrator using PowerShell.

I'm able to get the setting using

Install-WindowsFeature Web-Mgmt-Console

Import-Module WebAdministration

$WsusPool = Get-Item IIS:\AppPools\WsusPool\
$WsusPool.failure.rapidFailProtectionInterval

Days              : 0
Hours             : 0
Minutes           : 5
Seconds           : 0
Milliseconds      : 0
Ticks             : 3000000000
TotalDays         : 0.00347222222222222
TotalHours        : 0.0833333333333333
TotalMinutes      : 5
TotalSeconds      : 300
TotalMilliseconds : 300000

But I get an error when I try save a change to the value

$WsusPool.failure.rapidFailProtectionInterval = New-TimeSpan -Minutes 30
$WsusPool | Set-Item

Set-Item : Specified cast is not valid.
At line:1 char:13
+ $WsusPool | Set-Item

Some data of the system:

PS C:\Windows\system32> $PSVersionTable.PSVersion

Answer 1

You can use Set-WebConfigurationProperty like this

Set-WebConfigurationProperty '//*[@name="WsusPool"]//failure' -Name rapidFailProtectionInterval -Value (New-TimeSpan -Minutes 30)

Here is a very helpful page on the subject

Answer 2

I know this is already answered but I had to dig deep in further and found this link where Michael Felkin has put together extensive property settings for IIS which I found marvelous. Kudo to him for doing that...

You can find all that info here

Here is the shorter version of that I used:

$appPool = New-Item "IIS:\AppPools\MyAppPools" -Force
$appPool.failure.rapidFailProtection = "False"
$appPool | set-item

Keep in mind that the last line is crucial here in order to set the changes.

Hope, someone will find it helpful! :)
