Fedora NetworkManager and dhclient help request

[Pete Snider]

Hi,

As numerous places of work are, I am in a mostly windows shop.  I'm
having problems with fedora network manager not setting the hostname
through dhclient to the windows dns and dhcp server.  There are 2
people here that are using Ubuntu without any problems.  I tried the
same setup but it fails.  I created /etc/dhclient-eth0.conf with the
following entries below and still not working.  The values do are in
/var/run/nm-dhclient-eth0.conf used by dhclient.

Any ideas on what to check next or how to resolve the issue.

thanks,

contents of /etc/dhclient-eth0.conf:
