VLAN Problem
MS 2k3 - DHCP Server - 172.16.3.1
- Scope1= 172.16.*.* - SN=255.255.*.*
- Scope2= 192.168.*.* - SN=255.255.255.*

ip address 192.168.1.2 255.255.255.0
ip helper-address 172.16.3.1
-----------------------------------------------------
Both switches can ping there own VLan IP addresses from telnet. Switches can ping each other using the 172 range - using the 192 they can not ping each other. Manually setting IP as 192.168.1.5 with correct subnet on a laptop and plugging into port 13 on PoE switch can ping 192.168.1.2 but not 192.168.1.1
All help greatly recived.

Re: VLAN Problem
Forgot to add the static (tagged) route between the two switches. Using a static assigned address of 192.168.1.5 can now ping both switches from the laptop on the PoE switch.
I now can't get the DHCP to assign IP address to the laptop from our server.

Still not getting Ip's off the DHCP. I have plugged in to F2 on the Main switch and it still didnt get DHCP ip. Manually assigned IP can ping 192.168.1.1 and 192.168.1.2
Could it be the DHCP server itself ? 172's hand out okay. Would I need to add a second IP onto the Nic interface?

Re: VLAN Problem
Seems its DHCP-relay problem or DHCP server. I've attached jpeg of DHCP server nic settings and scope settings.
