				Re: Strange problem after SP3
			 
 
			
			This is clearly a widespread issue. I'd suspect a clash between certain NIC drivers and some component in SP3. 
 What I'd do in your situation is try a different brand of NIC. Preferably one using a different chipset.
 
 Bear in mind this is only a guess. NIC cards are cheap so it's a low-cost experiment.
