point to new dhcp server

I'm attempting to replace the existing small LAN dhcp server source on a win2003 server with the dhcp server function located in my firewall. I've configured the firewall from Sonicwall instructions. The win2003 dhcp server is stopped and deauthorized. However, at a workstation on the LAN, after renewing the lease, the new DHCP server is not found.

How can I make the workstation seek and find the new DHCP server? Does the workstation scan for DHCP server?

Try stopping and restarting the dhcp client service on the workstation (or reboot the workstation).

Hi there,

There are a couple of reasons you may be seeing this:

One possibility could be that the address is being bound to the NIC (network card)
go into the network settings and ensure that it is set to obtain an IP address automiatically (DHCP Client)

Rather than renew, try release (ipconfig /release) and finally another daft one I've seen is unplug the cable leave out for a few secs (wait for the no network detetcted message) and plug it back in.

Failing that if you could give me the info from running "ipconfig /all" on the problemsome machine and a working machine I can help further.

Hope that helps

@edgerep:
Many firewalls, including Sonicwall, require that you "double-enable" DHCP.  In other words, you have to enable DHCP, but also enable the configuration or DHCP scope.  Sure, this is usually done by default when you configure the scope, but worth double-checking; especially if you've already verified that your client PC is on the same network segment as the firewall and ipconfig /release followed by ipconfig /renew isn't working.

Let me know if I can answer any more specific questions for you.
