POHow do I recycle an IIS AppPool with Powershell?
text
Body
copied!<p>I haven't really done any Windows scripting at all, so I am at a loss on how to pull this one off. Anyway, basically what we want to do is have a script that will take an argument on which IIS AppPool to recycle. I have done some research on Google and haven't had much success on getting things to work.</p> <p>Here is what I am trying now:</p> <pre><code>$appPoolName = $args[0] $appPool = get-wmiobject -namespace "root\MicrosoftIISv2" -class "IIsApplicationPools" Where-Object {$_.Name -eq "W3SVC/APPPOOLS/$appPoolName"} $appPool.Recycle() </code></pre> <p>and the error I get:</p> <pre><code>Get-WmiObject : A parameter cannot be found that matches parameter name '$_.Name -eq "W3SVC/APPPOOLS/$appPoolName"'. </code></pre> <p>Anyway, it would be nice if I also knew how to debug things like this. I already fixed one bug with the original script by doing gwmi -namespace "root\MicrosoftIISv2" -list. Any other tips like that one would be great.</p> <p>Thanks!</p> <p><strong>Update</strong>: Here is some more info</p> <pre><code>$appPool = gwmi -namespace "root\MicrosoftIISv2" -class "IISApplicationPools" | Get-Member .
