SOLUTION:


This Particular error is trivial, yet has contributed to countless headaches.
It occurs in many cases when IIS is installed after .NET 2.0.
To fix it, download Microsoft .NET Framework 2.0 once again and perform a "repair installation".
The "repair installation" feature is available in the .NET 2.0 Redistributable Version
