I currently manage 2 web farms one is a .Net environment that hosts approximately 40 websites that have Information about the brand and products. The other is a mix of Classic ASP and .NET that hosts 10 sizable eCommerce sites. Each Web Farm has 3-6 Web Servers in the Farm and both are behind a redundant pair of NetScalers.

I attended an IIS class by http://www.accelebrate.com/ about a year ago on sight. It was directed for inexperienced users so I didn’t get much out of it. The one thing that was brought to the table was a batch file that moves all IIS folders to another drive. moveiisroot.bat. You can find the script on this blog post here. The problem I encountered with moving the Inetpub folder to a different drive was a bunch of warnings in the application logs. Here is the warning I was finding:
