    Hello

    I need help with relay agent on Sever 2008 (All are 2008 r2). Network:

    • DC (DHCP,DNS)  subnet 1 192.168.5.x (5.2 for DC)
    • Relay Agent ;config; for DHCP sever 192.168.5.2, listen on eth2  (there is no DHCP)
    • other side: 2 Servers

      Here is PIC

    PIC2

    I can not get IP. Relay Agent on 2nd eth should get ip from DC? Those 2 servers also. On RRAS in Relay Agent i see Requests Recived but 1/3 rejected and none Answerd?? Do i need to make some changes to DHCP?

    THX

    Hi,

    Thank you for the post.

    I assume your relay agent server ip addresses are 192.168.5.10 and 192.168.6.10.
    1. Turn off firewall on relay agent server, ping 192.168.6.10 from DC server(192.168.5.2). If ping result show failed, you need to add static route on DC server via command: route add 192.168.6.0 mask 255.255.255.0 192.168.5.10
    2. Verify if you have created 192.168.6.0 DHCP scope on DC server. DC will search the same subnet scope for the relay agent packet source ip 192.168.6.10.
    3. Other common troubleshooting, please read Troubleshooting the DHCP Relay Agent article

    If there are more inquiries on this issue, please feel free to let us know.

    Hi,

    Please verify the 192.168.6.0 DHCP scope options settings:
    003 Router                    192.168.6.10
    006 DNS Servers           192.168.5.10
    015 DNS Domain Name  Domain.com

    Otherwise, try to  add domain when computer connected to 192.168.5.0 subnet.

    003 Router                    192.168.6.10
    006 DNS Servers           192.168.5.2  (This is my DNS server, if i put interface from Router 5.10 in scope he says that there is no DNS server, but does not work, tried anyway).
    015 DNS Domain Name  mydomain.com

    Worked when connected to 192.168.5.0 subnet, but purpose of this testing was to simulate real situation which i ll have soon.

    Hi,

    Please ping mydomain.com from your client.
    In addition, post the client ipconfig/all result to us.
