isc-dhcp3-server issues with windows 2000 client

[Joe]

Hello, 

   I tried posting under a similar topic, but not sure if it went through.  I'm new on this list, but not a total newbie.   I have  upgraded a system from  p6 to p7.  Everything seems to be working on wtih the upgraded system except for dhcp.

   I have a backup of the old system and am using that to trouble shoot.  I have narrowed it down to the dhcpd binary.  If I put in the newer binary built with p7 it does not work with windows 2000.  If I put in the old binary it works fine.

Old Binary ( tcpdump ):

FreeBSD clients seem to be able to obtain a new address with no problem.

My question is how do I trouble shoot the two binaries?  What tools can I use?  How do I get dhcpd to actually put out debugging info to the syslogs or on the command line?  I've tried the -d and got nothing.

any help is much appreciated.

Thanks, 
Joe
