The Solaris DHCP client is embedded within the ifconfig program.

So to release a lease on Solaris:

ifconfig $int dhcp release

and to aquire a new lease:

ifconfig $int dhcp primary

And to get the current state:

ifconfig $int dhcp status

Where $int is theinterface name, such as hme0, bge0 etc.

There's no way to force it to do this from the server though.
