tempermental ip

Please excuse my long windedness.

I have one client that seams unable to hold the ip assigned to it.  The client 
is a toshiba laptop with vista on it.  I know about the broadcast issue with 
vista.  This problem does not seam to affect an acer laptop with vista 

There should not be a signal strength issue because the access point is within 
20 feet, and no obstructions.  The access point is a Netgear router that is 
only functioning as a switch.  DHCP, DNS are both taken care of by a Debian 
Linux (lenny, no gui) powered firewall server.  It is using dhcp3-server 

Architecture: i386
Source: dhcp3
Version: 3.1.1-6+lenny3
Depends: debianutils (>= 2.8.2), dhcp3-common (= 3.1.1-6+lenny3), lsb-base, 
libc6 (>= 2.7-1), debconf (>= 0.5) | debconf-2.0

The ip is a static assignment from the dhcp server so that local  dns works.  
I don't know if the client has done anything to his vista install to 
disable/change the way it is handling the broadcast flag.

From my google searches I have seen that the dhcpd.conf file needs to have an 
entry 'server-identifier {server name}' that is pointed correctly before vista 
will work correctly.  I have an entry 'server-name {server-name}'.  Is that 
the same thing?

I have not tried the broadcast entry in the config file that I have seen some 
people recomend.  The client is only hear for about 4 hours a week.  But I am 
getting tired of listening to him complain.

The dhcpd.conf
