Resolution

This is due to the network identity having insufficient access for ASP.NET. Verify that the user, group, and/or application pool identity being used have write access to this folder. Refer to http://www.iis.net/learn/get-started/planning-for-security/understanding-built-in-user-and-group-accounts-in-iis and Isolating Applications under http://technet.microsoft.com/en-us/library/dd163542.aspx for more information on appropriately configuring these accounts.
