Problem using subclasses, getting no free leases

[Uddenhed, Marcus]

I can't get the use of subclasses in dhcpd.conf
it says that there are no free leases, below are the dhcpd.conf file,
tcpdump from the dhcpd server and the logmessages in the messages log.
 
What am i doing wrong.
 
The clients are primarily Windows machines if that could be an
tip in the right direction on the error.
 
I've used the following rows to instead of the match hardware-address
under class "test" clause.
"match hardware;" & "match pick-first-value (option
dhcp-client-identifier, hardware);" but with no difference
in the outcome.
 
Thanks in advance
