ISA 2004 needed sp2 to properly load

Phil had installed SBS 2003 on a 2 processor, Dual core Xeon so = 8 logical processors... he then installed ISA 2004 and got the message:

The ISA Server Standard Edition cannot run. Either the server is using more than 4 processors, or it is configured to use the Active Directory service.  Use the source location 100.371.4.0.2163.213 to report the failure. Contact Microsoft (R) Corporation for more  information.

..and after reboot the ISA services would not restart.  Ended up he had to install ISA 2004 sp2 to get ISA to function on this spec of a machine.

2 processors with each processor running in dual mode is the equivalent of saying 2 + 2

as far as I understand it 2+2=4 and not 8?  please elaborate

Dual Core Xeon's Support Hyper Threading.
2xProcessors x 2 Cores =4 x2 Hyper Threads = 8
