Symptoms

Consider the following scenario:

  • You configure the identity of an application pool to use an account on a computer that has Microsoft Internet Information Services (IIS) 7.0 or Microsoft IIS 7.5 installed.

  • The account uses the "domain\user" format, and the Load User Profile option is set to true in the advanced settings of the application pool.

  • The user account has never been used to log on to this computer. Therefore, the user's profile directory was not created in Drive:\users.

  • A client request is sent to a site that is hosted by the server running IIS.

In this scenario, no local profile folder is created for the custom identity that you configured for the application pool.

Note When this issue occurs, a temporary folder that is named TEMP is created in Drive:\Users, and this temporary folder is deleted when the IIS worker process (W3wp.exe) exits.

Cause

The issue occurs because IIS passes a "domain\user" formatted value into the LoadUserProfile API, and this API attempts to create the user profile folder. However, the "domain\user" format is not a valid format for the folder name. Therefore, the folder creation attempt fails, and the issue that is described in "Symptoms" section occurs.
