Symptoms

If you encounter the following error in your web application (things hosted in IIS) “The configuration section <sectionName> cannot be read because it is missing a section declaration " 

 

examples

“The configuration section 'standardEndpoints' cannot be read because it is missing a section declaration”

“The configuration section ‘tracking’ cannot be read because it is missing a section declaration”

then you need to install either SP2 of Vista/Win2k8 or the hotfix mentioned in KB article 958854.

 

I would actually recommend anyone trying out 4.0 Beta1 bits always install the hotfix below.
