You are getting too many collisions on the interfafce.  Look at the directly 
connected network segment with a sniffer.  Is the link over 40% utilized?  
Is one host generating a Lot more traffic than the others?  Could that host 
have a bad nic?

Is there one PC that always has trouble logging on or accessing network 
resources?  Could it have a bad nic?

Do you have too many hosts on that network segment?  how about questionable 
cabling?

I think there is a command to increase the threshold that triggers the 
collision auto-shutdown, but you should fix the source of the problem, not 
the symptom.

Good Luck,
