Thanks so much for the replies.  (And on the weekend, no less) 

The clients boot up now, but it takes almost 10 times longer than 
before on the other switch.  Performance seems fine once they've 
booted.  There are a lot of messages throughout the bootup process 
saying "nfs server not responding" followed by "nfs server OK".  It 
eventually gets there, but I can't really function with bootup times 
this long.  One thing I noticed is that it said that it had only 
negotiated 100BaseT, half duplex.  Could that be causing the slowdown?  
I told the switch to auto negotiate, but to default to full duplex 100, 
should I force it to full 100?

Any further tweaks I can try to speed up the boot times?

Thanks,
