Symptoms

Applications may stop responding or may encounter other function failures if these applications call the LCMapString function on a computer that is running Windows Server 2008 or Windows Vista. For example, because of this problem, Exchange Server 2007 may stop responding or may encounter index corruption.

Cause

The LCMapString function uses a mapped section of a Unicode table to sort strings. However, the system does not set correct discretionary access control list (DACL) settings for the mapped section. When the mapped section that has the incorrect DACL settings is accessed by lots of threads at the same time, the LCMapString function randomly returns incorrect results.
