    hello i need help with my lab. i believe i don't have it configured correctly.

    i have 2 ip ranges 172.16.0.x and 192.168.1.x.
    i have 1 DC 192.168.1.xxx. it has configured the 192 and 172 which works well because "nslookup" works for any machine in any of the 2 ranges.
    the problem is that the 172.16.0.x range machine can't do a Windows Explorer Network look-up on the 192 range.

    the DC only has one NIC card. it is a Windows 2003 OS.

    what am i missing?

    I am not sure I get the picture...you have 2 subnets connected to a domain controller with one nic? How? Please try to be more specific.

    i have a LINKSYS router that allows me to support multiple subnets. currently i'm only using 2.

    but i only have 1 domain controller to provide DNS on the windows domain.

    If you are trying to see the computers from subnet 2 while connected to a pc on subnet 1 in the Networking area then the computers are not using DNS but are using NetBios broadcasts and the computer browser service (or LLMNR for vista/win7 wich uses multicasts). By default routers don't forward broadcasts between subnets unless configured explicitly to do so (if available).

    In your situation you would need a WINS server, it will provide single labled name resolution across subnets.

    WINS provides the following benefits over other NetBIOS name resolution methods:

    • WINS name resolution reduces NetBIOS name query broadcast traffic because clients can query a WINS server directly instead of broadcasting queries.
    • WINS enables the Computer Browser service to collect and distribute browse lists across IP routers.
    • The WINS dynamic name-to-address database supports NetBIOS name registration and resolution in environments where DHCP-enabled clients are configured for dynamic TCP/IP address allocation.
    • The WINS database also supports centralized management and replicates name-to-address mappings to other WINS servers.
    • WINS and DNS can be used in the same environment to provide combined name searches in both namespaces.

    i'm not able to configure the WINs correctly been trying off and on.

    i'm missing some step.

    what document on line i found leads me to believe this is simple but i'm sure i'm missing something.

    i also going to see if the router can do the broadcast forwarding?

    WINS can be configured in the following modes. Just configure routing between your subnets and configure WINS servers in each subnet as push/pull replication partners.

    Also have a look here maybe you've missed someting simple, I know I do...http://technet.microsoft.com/en-us/library/cc781979(v=ws.10).aspx

    If it is still unclear, please give more details about what you are having trouble with and I will try to help.
