DHCP Problems

[Rodrigo Cechinel]

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,

Is the DHCP address pool big enough for your network? You might be running
out of available addresses.

Sounds like your DHCP is overlapping. The servers
shouldnt have the same range.

example

server A
10.0.1.5 - 10.0.1.203

Server B
10.0.1.110 - 10.0.1.203

110-203 are duplicates. Make sure you dont have something
like that setup. The other thing you might want to double
check your setup.

Good luck
