_dhcp user problems

[Anthony M. Agelastos]

Hello all,

During the upgrade to 6.0, I may have created the user _dhcp  
incorrectly. I was made aware of the problem when I noticed the  
message during boot:

Setting hostname: ast.home.iq.
rl0: link state changed to DOWN
rl0: no link ....rl0: link state changed to UP
got link
no such user: _dhcp, falling back to nobody
DHCPREQUEST on rl0 to 255.255.255.255 port 67
DHCPACK from 192.168.0.1
bound to 192.168.0.4 -- renewal in 129600 seconds.

So, as root, I tried to create them and delete them. This is proving  
unsuccessful. See below.

ast# pw userdel _dhcp
pw: no such user `_dhcp'
ast# pw useradd _dhcp -u 65 -c "dhcp programs" -d /var/empty -s /usr/ 
sbin/nologin
pw: user '_dhcp' already exists

Are there any recommendations? I am running FreeBSD 6.0-STABLE. Some  
additional information is below. Thank you so much for your  
assistance. I checked the mailing list as well as Google and did not  
find a fix for this particular problem. I found someone mentioning  
that the database may need to be rebuilt (however I have no idea how  
to do this).
