I've reproduced this with a vanilla 2kSP4 install (IE 5) and all patches up to the latest and 
greatest. I've tried with Leo's win2k-hack patch that only delays every 16th (iirc) irq and that 
seems to work also, but perhaps it was not as reliable (I've done so many tests my memory may not be 
that flash).

Anyway. -win2k-hack gets windows update working on 2k here also.
