DHCP Not Leasing Addresses

[kevinmclarke]

Hi,

 

I have the following setup;

 

ESX 3.5 update 3.

VM Image Win2k8 Core server setup as AD, DNS, DHCP

VM Image Win2k8 Full server setup with Exchange 2007 and Remote Management.

 

Active Directory is set up and looks OK, as does DNS. I can contact both servers from my laptop by address and name.

 

I have set up DHCP ipv4 as I have done for many other versions of Windows. The scope is active, the server has been authorised in AD. When I try to get an address, it thinks for about a minute and then tells me that there are no DHCP servers.

 

The event log does not show much. I disabled the firewall on both machines, but still had to add a rule to enable the remote viewing of the event log, could this mean that the firewall never actually turns off?

 

I also tried setting up a test VM image of full server and installed DHCP and two NICs, one static and one dynamic. Still that machine cannot get an address from either server.

 

I have tried a basic network switch in place of our HP Procurve just in case that was causing some problems but no dice. I have tried using a port scanner that tells me the ports are not open but I have entered the cmmands on the server, which tells me they are open. I did try a program called DHCPExplorer but it did not come back with anything. Captured the packets with Wireshark but it only showed the machine asking for an address, no feedback from the server.

Your DHCP server should have Static Ip in the same network as the DNS/AD. Or Routing & remote access should be enabled

 

If there is a router in the network to forward broadcasts

The DHCP server does have a static IP address of 192.168.2.1, it is acting as DNS and AD also. I have another machine acting as router with IP 192.168.2.254. I can manually assign IP's in the range 192.168.3.0 and these can communicate without problems.
