Since about a month ago, I had been unable to view local MSDN documentation due to a problem with Microsoft Document Explorer. It would give a warning about being unable to display the page, unspecified error. This problem started appearing after an SDK update or maybe it was an SQL Server update. Anyway, no amount of uninstalling and reinstalling the various related applications could fix this problem. It turns out that the solution to this problem is just to simply clear all your Internet Explorer Browsing History. Hope this info will help others that may be having the same problem.
