The AppCmd command is your one-stop-shop for administering Windows Server IIS web servers. In combination with WinRM it’s your Swiss Army knife for your daily routine. This post introduces appcmd and provides you with a lot of helpful appcmd examples.
By default, an IIS application pool (or “AppPool”) recycles on a regular time interval of 1740 minutes, or 29 hours. One reason for this time interval is that application pools don’t recycle at the same moment every day (every day at 07.00 for example). However, sometimes you want to change this regular time interval to a specific time schedule. And when you try to configure this in IIS Manager, it gives you an error. Luckily, AppCmd and PowerShell come to the rescue!

In my routine, I occasionally have to start multiple website application pools when they are in a stopped state. On more than one web server. Being a lazy system administrator, I find it too much work to log on every server. Therefore I start those application pools in a loop.

This is because I set autostart to false when I disable hacked websites, and those application pools may not be started until all problems are resolved of course. To start application pools, I use the AppCmd command.

Some think AppCmd is very limited: if you don’t know the options to use, you may think you can only address the x64 .NET Framework version, or only x86, or you can only target the current active .NET Framework version. Fortunately this is not true, you can address both x86 and x64 versions of .NET with AppCmd. Read how…
How to use PowerShell to create websites and application pools in IIS… A client of the company I work for wanted to quickly add 60 sub-domains to his website. But, the sub-domains had to be created as self contained IIS websites, and running in their own application pools.

This made our task a bit easier, because we could easily script this in PowerShell
