I don't know what to say. I think I installed one million times this server and configure it secure.
I never had any problems.

Check to see if you have any of the following services disabled (if they are not there, you don't need them):
Event Log
IIS Admin Service
License Logging Service
MSDTC
Protected Storage
Remote Procedure Call (RPC) Service
Server
Windows NT Server or Windows NT Workstation
Windows NTLM Security Support Provider
Workstation
World Wide Web Publishing Service

Also, open Administrative Tools > Computer Management
Click on Event Viewer and look into those sections:
Application - any errors related to services there?
System - any errors related to services there?

I'm getting to a point where I exhaust all my answers to your IIS problem.
As a curiosity, why did you disabled Terminal Services? I hope you did not followed those crazy tutorials where they tell you how to "secure" your PC. In fact, they teach you how to break it.
