WORKAROUND
To work around this problem on a computer that is running a PAE kernel, add the /NOPAE switch to the Boot.ini file. To work around this problem on a computer that is running a PAE kernel with data execution prevention (DEP), add the following switch to the Boot.ini file:

/NOPAE /NOEXECUTE=alwaysoff

When you add the /NOPAE switch to the Boot.ini file, the computer cannot use all available memory.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.
