A good tool for finding out if a particular IP address is in use is
arping. Try the "-D" option for duplicate detection. You can do this
with the interface up, but with no address assigned.
IIRC, some DHCP clients will do this automatically before accepting an
address, and should request another one. You can often configure your
DHCP client to request a specific address, and that might help. Take
a good look at the manual for your DHCP client to see what other
options it has that might help, and to help debug the problem. You
could also try a different DHCP client; maybe something your DHCP
client is doing is confusing the Windows server. There are several
DHCP clients available for Linux which are in wide use; the ISC DHCP
server is probably the oldest and so may be the most likely to be
compatibility-tested.
Good luck,
