I have a SQL Windows 2000 server running on Windows 2000 server.
The computer has 2 processors installed. During booting up it shows those 2 processors in the boot message. The bios shows the same amount of processors but the task manager shows 4 processors.
I ran SFC on this computer, installed SP4 on Windows 2000 server and SP3 on SQL.
When I  switch to uniprocessor mode it shows just one processor.
Is there any possibility to fix this issue without reinstalling the windows ?

This is due to the Intel Xeon processors you have in your server. It's called hyper-threading technology which is supposed to boost the performance of the machine but it often causes problems with certain applications. I definitely recommend you disable it (as I did on my servers) so as to avoid any problems in the future. You can go into the BIOS to disable it. Unfortunately, I can't tell you where in the BIOS to go to disable it since I don't know what type of BIOS you are using but it shouldn't be too hard to find.
