Win XP as Bind client

[V@dim]

In my office is FreeBSD server and Windows Xp clients.
On FreeBSD pc is DNS (bind), Apache, Squid, ... .
On my home pc i want configure also FreBSD server, wich I
have installed in VMWare Virtual Mashine under Windows XP.
I have configured bind, resolv.conf, rc.conf the same as
my office freebsd server. But i can't understand one thing.
Any my office windows xp client:
1. Lan settings -> DNS is FreeBSD pc IP
2. DHCP is off.
3. DNS suffix is empty.
For example office domain's name is office.net and server name is serv.
 From my office xp client i can:
1. ping serv.office.net
2. ping serv
My home xp pc i have configured same as in office.
For example my home domain's name is home.net and server name is hserv.
 From my home xp client i can only ping hserv.home.net, i can't ping
hserv without domain name. Why? Help to solve this problem.
