Programs (such as Microsoft Internet Information Server) may stop responding (hang) while they are attempting to gain access to files on a remote server.


The Windows NT Redirector (Rdr.sys) may hang threads while trying to close a file because of a problem in the cache manager. These threads wait for an event that never happens.
