I don't think I've ever seen that happen under vmware server - and I've had 
guests up for at least a year without reboots.  With player I've normally 
stopped the guest before disconnecting from the network.  Are you using bridged 
or NAT?

I've never seen a problem with DHCP on bridged connections under any circumstances.
