I have a hybrid network (Win2k, Win95, Win98 and WinME). 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 all right. Some days later, I received a call from a user (normally, Win9x user) saying that he can't use the network services because it's showing an "IP conflict message." When I go there and run winipcfg, I see this configuration:
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 five days later start)
I checked our DHCP console and that IP address was given to another client. I've been asking a lot of people about this, but no one seems to be able to help me. I even asked my teacher for my MOC2153 class and he had never heard about it before.
