Enable client DHCP logging ?

[Palle]

Is it possible to enable client DHCP logging ?
The reason for asking is that we have clients (Win 2k pro) roaming between
subnets and sometimes when they boot up att a new subnet they don't get a
address relevant to the current subnet, instead they get the old address. We
have 2 DHCP servers (Win 2k Server) providing services, one in the
156.51.10.x subnet, and one in the 156.51.3.x subnet, they are providing
superscope for each other in case that one goes down. Extract from the
servers DHCP log:
The client in this case is supposed to renew at the DHCPserver 2.

DHCPserver 1

10,03/31/04,07:55:23,Assign,156.51.70.12,LTPST18001.company.se,00034791E618

11,03/31/04,08:10:18,Renew,156.51.70.12,LTPST18001.company.se,00034791E618
11,03/31/04,09:09:12,Renew,156.51.70.12,LTPST18001.company.se,00034791E618
10,03/31/04,09:32:16,Assign,156.51.70.12,LTPST18001.company.se,00034791E618
11,03/31/04,09:32:21,Renew,156.51.70.12,LTPST18001.company.se,00034791E618

DHCPserver 2

15,03/31/04,08:01:32,NACK,156.51.70.12,LTPST18001.company.se,00034791E618
15,03/31/04,08:10:13,NACK,156.51.70.12,LTPST18001.company.se,00034791E618
15,03/31/04,09:32:16,NACK,156.51.70.12,LTPST18001.company.se,00034791E618
10,03/31/04,09:40:04,Assign,156.51.10.39,LTPST18001.company.se,00034791E618

The final Assign is accomplished by manually cleansing each DNS, WINS and
DHCP of all refersnces to LTPST18001.

Any ideas ???

Hello,

You can enable logging on the DHCP server.

Open DHCP. In the console tree, click the applicable DHCP server. Right
click the applicable DHCP server. On the Action menu, click Properties. On
the General tab, select Enable DHCP audit logging, and then click OK.

As you could see in my first post, there are some snippets from the DHCP
server log, my wish is to log on the client as well, in order to get some
new inputs on the problem.
I've noticed that there are similar registry keys on the client regarding
the dhcp service to the server dhcp service, but I can't find any
documentation or tips on what keys to add or change...
