<DIV><FONT size=2 face=Arial>After making several tests (using a small C#
program I wrote to count the number of cores using this API), </FONT><FONT
size=2 face=Arial>I'm able to report that this is indeed
a bug with Windows Server 2003 and Windows XP Pro
x64 SP2, and I'm glad to report that installing KB932370 resolves this
problem.</FONT></DIV>
<DIV><FONT size=2 face=Arial>This bug is not present in Windows XP Pro SP3 (32

somewhere.</FONT></DIV>
