This is an update to the ntdll.dll that shipped with the version of Win32s 
included in the October release of the Win32 SDK for Windows NT.  This has 
not been through the normal testing procedures, so you are highly advised 
to use this at your own risk.  It is reccomended that you back up the 
original ntdll.dll, as well as any important data on your machine.  This 
update has not been observed to cause data loss, but since it has not been 
through the usual testing, we cannot be responsible for any data loss that 
may result from using this.
