IP Conflict using DHCP Server

[=?iso-8859-1?Q?Rodrigo_Bar=E7al?=]

I'm brazilian and i apologize for my possible mistakes.
I have a hybrid network (w2K, w95, w98 e wme). I have two
windows 2000 servers, partners domain controllers. In one
of them, i have a dhcp server service running. It's
integrated with DNS (compatible mode) and WINS on the same
server.
My clients get a lease and everything is right. Some days
later, i received a call from a user (normally, w9x user)
saying that he can't use the network services because it's
being showed a "IP conflict message". When i go there and
run winipcfg, i see this configuration:
IP: 192.168.1.x
Mask: 255.0.0.0 (should be 255.255.255.0)
DHCP Server: 192.168.1.245 (right)
Start of lease: a normal date
End of lease: nothing! (should be 5 days later start)

I check on dhcp console, and that ip address was given to
another client.

I asked for a lot of people and nobody could help me.
yesterday, i asked for my teacher on MOC2153 that i'm
started on last monday, and he never heared about it
before.

Someone can help me, please?
Thanks,

Hi Rodrigo,

Tudo bem?

How many nics in the server? Have you set options 003, 006, 015, 044 and 046
(0x8) in DHCP-server?

Make sure that you install all the latest patches for Windows 98 machines or
use Windows 98 SE machines if possible. Also, some switches can cause this
if Spanning tree is enabled. You can also set the Windows 98 machines to
release their IP address on shutdown (search the KB for
ReleaseLeaseOnShutdown (make sure to disable fast shutdown if you decide to
use the releaseleaseonshutdown registry key.
