Hi Mario

On the windows PC open a DOS window and run  ipconfig /all

Do the values returned indicate that the PC got a valid IP address and
other settings corresponding to what is in dhcpd.conf?

What is in the syslog files on the Linux dhcp server in
/var/log/messages ? Does that show a conversation DHCPDISCOVER,
DHCPOFFER, DHCPREQUEST, DHCPACK between the server and the Windows
client?

On the PC can you run   nslookup www.wwlib.lan ?

If you get an IP address back from that, can you run    ping www.wwlib.lan ?

Is the DNS server configured with domain named for foobar.lan, or
wwwlib.lan, or both?
