As a former Sun SA, it was ALWAYS mandatory to lock speeds. Especially when
Cisco was involved. Sun and Cisco hardware has always had issues with auto 
negotiation. And when both vendors say it's the other's fault, you just do
what's best for your environment. As for Windows, I'm not too clear on that.
But if you never want to run into any issues, it's way best to lock speeds
and duplex on BOTH sides. That way you can never go wrong.

We've had more problems in the old days with people "forgetting" to
hardcode, than we've had in recent years leaving everything auto.

However, on the recommendation to only hardcode the
client......absolutely NOT.
The standard behaviour (for one side hardcoded, and the other Auto) as
outlined by the IEEE is to go to HALF-duplex. 

NOT what you want.
