IIS Manager does NOT start and you receive a message similar to:

Snap-in failed to initialize.
Name: <unknown>
CLSID: \{A841B6C2-7577-11D0-BB1F-00A0C922E79C\}

This behavior is symptomatic of the Inetmgr.dll library not being registered.

To resolve this problem:

1. Open a CMD.EXE Window.

2. Type regsvr32 C:\Windows\system32\inetsrv\inetmgr.dll and press Enter.

3. Press OK to acknowledge success.

4. Close the CMD.EXE window.
