The most common cause of problems accessing this specific file involves the Indexing Service contending with ASP.NET, which results in the hash.web file becoming locked.

To fix this issue, disable the Indexing Service and then rename or delete the website temporary file directory (C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\TemporaryASP.NET Files\npc for instance).
