Server Down - How should Client Act?

[Melody Helt]

I have my default lease set up for 3 mins for experimentation.  I am giving 
out a static IP based on MAC address.

My server does down.  Using ethereal to watch the network traffic, I see 
that at about 1/2 the time of the lease, the client sends out a DHCPREQUEST 
message then 5 seconds later sends out another DHCPREQUEST.  Nothing else 
happens.

After the lease time expires, the server starts up again.  No communication 
occurs between client & server.  The client has to be rebooted in order for 
it to communicate & get an IP from the server.
