Win 2k will support multiple CPUs... provided it detects them during installation. P4 Hyperthreading may need a special driver... I'm not sure.

Your best bet is to slipstream Service Pack 3 and make a custom install CD. It really does work better that way.

Slipstreaming instructions are here: <A HREF="http://www.thetechguide.com/articles/slipstream.html" target="_new">http://www.thetechguide.com/articles/slipstream.html</A>
SP3 is the same as SP2, except the semifore file is named cdromsp3.tst.

Instructions for Making a bootable win2k CD are here: <A HREF="http://www.svrops.com/svrops/documents/winbootcd.htm" target="_new">http://www.svrops.com/svrops/documents/winbootcd.htm</A>

Win2k Pro supports upto 2 cpus so it will probably support HT.

All versions of Windows 2000 as well as all 32-bit versions of Windows XP and Windows .NET Server support HT. The rest don't.

Only XP benifits from HT. While Windows 2000 does see 2 logical processors, it cannot distinguish between real and virtual (logical) CPUs so it acts as if there are really 2 CPUs in the system and manages resources accordingly. This degrades performance (according to Anandtech.com in some cases ~20 percent). XP 'knows about' HT and virtual processors so it's designed to benifit from it. Read Anand's article reviewing the P4 3.06 and it answers your question.
