DHCP doesn't release new IP address

hi All

I have below setting

1. Win2003 DC under Domain A
2. WinNT4 DC under Domain B
3. Win2003 DC under Domain C

Domain A and Domain B is trusted
Domain B and Domain C is trusted
Domain A and Domain C is NOT trusted

I have existing DHCP server Win2000 named Server1 (Server1 IP is 172.22.x.x)
under Domain B is release existing IP range from 172.22.x.x to user, since
this DHCP server is under Domain B, therefore it doesn't get required
authorised from Domain A and Domain C, and it working fine.

I had just setup a new DHCP server named Server2 at Win2003 DC Domain C (IP
is 10.215.x.x) that resided at the same box that going to release new range
of IP which is 10.215.x.x to user, when everytime this DHCP services is
started it some how make Server1 DHCP stop reason given is unauthorised, BUT
i have already authorised it at Domain C.

Since i required the new IP range to be release to user, I had stop the DHCP
service at Server1 and hope the Server2 DHCP is releasing new IP 10.215.x.x,
but the luck is not at my side, user PC fail to get the IP address, even the
ip-helper had configure at router end

I had running out of cure, any suggestion are welcome

thanks in advance

Hello gbkhor,

Is this related to the "how to authorised standalone DHCP server" posting
some minutes later?

Hello gbkhor,

Let's talk only about the problem domain, C in your case. That you have trust's
between them shouldn't have any influence on the DHCP. The trust allows ressource
access to other domain, but DHCP is not involved.

Please post an unedited ipconfig /all from the running DC/DHCP server and
the new one. Check the system log for DHCP errors and post them here complete.
Can you ping the server from a client with ip address, servername and FQDN?

Do you use more then one NIC in the server, then make sure DHCP is binded
to the correct NIC for the subnet.
1. Open the DHCP console
2. Right-click the DHCP server in the console tree, and select Properties
from the shortcut menu.
3. When the Server Properties dialog box opens, click the Advanced tab.
4. Click the Bindings button.

Best regards
