Error 1:

Cannot complete the operation. An unexpected error occurred.

The problem is in the ClientCacheDirectoryForInstance property on the TeamFoundationServer class.

The problem was fixed by giving write permissions for the application pool to the Cache folder.

The Solution

Enable Integrated Windows Authentication and Turn Off Anonymous Access

Open inetmgr, right click “Web Application” and choose properties.

Select “Directory Security” and enter “Authentication Methods”

Clear all checkbox except “Integrated Windows Authentication”.

Create an Application Pool for a Web Application

Create a default application pool and enter the Identity  of the user name for the domain account under which you want your Web page to run in the User name field, using the domain\user name format.

Change Web Application to Work With the New ApplicationPool

This will fix the problem.
