    Hi Team,
    Please my find query, bear with my english.. help me to find where i exactly did the wrong….
    I have configured the Testing LAB on Vmware workstation to test the DHCP relay agent configuration.
    This LAB contains 3 systems.
    · One is Domain Controller with DHCP, DNS services installed. Configured with below IP address.
    o Ip: 192.168.1.224, default gateway 192.168.1.1. and Preferred DNS : 192.168.1.2

    · Second one is also a Server is configured as Router, Configured with below IP address.
    o NIC1: 192.168.1.124
    o NIC2: 192.168.2.124
    Configured the router and checked by configuring the static ip on the client as 192.168.2.9, successfully got the ping reply from the server (Domain Controller).
    · Third one is a client system installed with XP SP2 professional operating system. Configured as Obtain an IP address automatically.

    1. Configured DHCP server with scope range 192.168.1.10 – 20, DHCP server successfully given the ip to Client System. For time being disabled.

    2. Now configured with scope range with 192.168.2.0 network, the range is 192.168.2.10 – 20, Configured the DHCP Relay agent on the Router successfully.
    When configured the client obtain IP address automatically, Client system not getting ip from the DHCP server, but in the DHCP console it’s showing on the scope of 192.168.2.10 – 20, in the Address Leases, one IP released to the client. But client keep on trying to get the IP address…
