Solution found.

John Martinez suggested I look at the ARP cache on my Sun or the ARP
table on the router. I checked the arp cache on the server and it was
empty. I also found some more messages in the log that looked like

Nov 18 16:25:59 <host> ip: [ID 903730 kern.warning] WARNING: IP: Hardware
+address 'YY:YY:YY:YY:YY:YY' trying to be our address zzz.zzz.zzz.zzz!

The YY'd MAC address is not my MAC address, but the zzz'd IP address
is my IP address.

John suggested it looked like another machine was grabbing the IP
address -- which, as it turned out, was the case. Not sure why it
happenned in the first place, but the network admins eventually gave
the offending printer a new IP address, and all is well now.

Other suggestions included DHCP server problems, especially if it's a
windows server (John Martinez), and a failed switch (Ed Alexander).

Thanks all -- my first experience on this list, and it's a great
resource :)
