MSDTC Not Installed on New Dell Computers

I had this issue when I ran IIS for the first time:

The server failed to load application '/LM/W3SVC/1/ROOT'. The error was 'Class not registered'.

The problem was Dell did not install the MSDTC, which is the Microsoft Distributed Transaction Coordinator, and I found the solution at http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=881749&SiteID=1.

Basically here are the steps that I took to fix it:

1. Run msdtc - install in c:\windows\system32 using the command prompt


2. Uninstall and reinstall IIS
