I'm stuck with that problem at the moment: there was a short thread about
Win2000 with dual processors in the german IB ng, the result seems there is
currently *no* soultion to the problem. (Please anybody correct me if i'm
wrong!)

To quote Christain's quote of my own msg :-)

The problem seems that under Win2k, setting the affinity mask appears to have
no effect, and thus does *not* stop the juggling. (to be more precise: win2k
does not allow one process to modify the affinity mask of another, which is
exactly what IBAffinity does with IBServer.)

If anyone has a solution to this (ore more insight to the topic of affinity
masks and maybe a workaround), i'd be very interested myself as i also have
to set up a dual-proc Win2k for IB shortly... and i'd really like a better
solution than to rip out the 2nd CPU ;-)
