Check the following:

netstat -i

Your error counters for Input/Output Errors should be zero or a very low number. If the I/O Error numbers are not zero, wait a couple of minutes and re-run the netstat command, as listed above, to see if the numbers increment. If they do, check your speed/duplex in /etc/system or using ndd. Your mileage will vary depending on what kind of interface you are using.

In regards to someone else using your IP address, look in /var/adm/messages. Normally /var/adm/messages will state something like this:

Hardware address 'xx:xx:xx:xx:xx:xx ' trying to be our address xxx.xxx.xxx.xxx !

If so, give the hardware address to your network admin. They will be able to trace it by the mac address and shutdown the offending port.

Also, check the following basics:

Can you ping your default gateway (if permitted on your network)?
Is the interface up?
Can you ping your own IP?
Can you ping another ip that is local to your network or vlan?

Is your default gateway set or wrong?
netstat -rn
If so, check /etc/defaultrouter and correct the parameters and
route change default x.x.x.x

*where x.x.x.x is the ip of the default gateway

Is your subnet mask correct? Check /etc/netmasks

Also, do you see broadcast packets on the line? Use "snoop -d interface" to see if any broadcast traffic shows up. Replace "interface" with your ethernet driver/instance (e.g. hme0).
