Yes it is SP4 sorry for not adding that.

ARRGGH :-(, I knew this was going to come back being a M$ thing Thank you 
for at least proving my sanity, but I almost wish that it was a stupid 
mistake on my part. 

Hey wait a minute... is not DHCP M$ baby?? How could they violate their own 
standard?? (Please do not mis-read this I am being critical of M$).

That is not a realistic option at least from a political standpoint at this 
time. I am attempting to replace the my company's ftp server with a FreeBSD 
box and hopefully that will open the door for more work being put over to 
this OS, but that is another discussion. 

I changed dhclient not to go into a daemon and just exit after setting up the 
interface and am excuting it from a cron job every 24 hours. The NT server 
gives out 72hour leases. Is there some other "gotcha" by doing this?? I 
realize that the IP will never clear itself if the cron job does not run but 
other than that will I have another problem?? Perhaps there should be a 
switch for this?? I don't like it either but it is a fact of life that we 
will have to use DHCP under Windoze at least in the begining... 

Also any reason why bpf is not in the generic kernal so a machine can get a 
DHCP IP "out of the box"??
