    The question I am about to ask may sound silly but please forgive me I am new in that filed.

    In my scenario I have windows 2000 server with IP 192.168.0.1 with internet access and 4 other computers connected to it and one windows 2003 server with IP 192.168.1.1

    that windows 2003 in running on Microsoft Virtual PC

    everything is working fine except the fact that there is no connection between that two networks.

    could anyone tell me how do I have to configure them to make the comunication possible?

    thank you

    see you missed one vital bit of information regarding networking
    and that is the subnet mask (or address)
    this defines what portion of that address is a network address, and which part is a host address

    im guessing your addresses are using the standard 255.255.255.0 (or /24) for that range

    here it is a bit more graphical

    192.168.000.001
    255.255.255.000

    as you can see, the subnet mask effects which half is a network address, and which half is a host address
    in this example
    192.168.0
    and 192.168.1 are two SEPERATE network addresses, this means they cannot communicate without routing

    your best bet would be to use the SAME network address with that server if you want it to communicate with the rest of the network
    ill explain more if that makes no sense, ask away :)

    yes I know that are two different networks and without kind of routing it wont work.

    the question is how to enable them to communicate
    the only gues I have is to install second network card and assign to one 192.168.0 network and to the other 192.168.1 network and bridge them.

    but as I dont have any spare NIC at the moment is there any other way round?

    You can set up a Windows Server to act as a router and yes you are right, it would need two NICs. This might help. Sorry, I can't find the instructions for enabling RRAS from the GUI. Microsoft support's search engine has always baffled me that way.

    is there any reason these machines have to be on seperate networks?
    whats the purpose here?

    I think the purpose is to learn how to join two networks, Phoenix - not being funny, but why not ask how to do it ?

    Soz if I'm wrong here ...

    i was just curious as to his aim, as it would help better solve the problem
    if hes just playing around thats great, and the fact that routing is involved he knows, which is also great, if its some other reason then perhaps we could come up with some other advice
    that was my position :)

    I've got scenario:

    create two separate networks:
    Firtst.
    IP 192.168.0.1 mask 255.255.255.0 for "server01" (windows 2000server)

    "client01" obtains IP from DHCP on "server01"


    Second
    IP 192.168.1.1 mask 255.255.255.0 for "server02" (windows 2003 server)

    "client02" obtains IP via DHCP on "server02"



    server01 hac ICS enabled and is connected to the internet

    server02 has two NIC one with IP 192.168.1.1 and the other one 192.168.0.50


    questions (problems to solve): :kngt
    1.if on the network are two DHCP servers how to "explain" client01 to obtain IP address form server01 and client02 form server02 - all computer are connected to the same switch.
    2.enable comunication beetwen that two networks - set up routing on server02

    I am not familiar with MS virtual PC but would guess it is something like VMWare? In VMWare you can enable the networking on the virtual machine to interact with the real network that the host is on by using bridged networking.

    Yep that is also available in MS Virtual PC and it;s working fine but now I'm trying to figure out how to configure routing service in W2003 and force them do this job.

    OK so finally I got it. I enabled Routing and Remote Access and in RAS server properties General tab I set Enable this computer as a Router for LAN routing only.
    In my routing table I ve got:

    destination | net mask | gateway | interface
    192.168.0.0 255.255.255.0 192.168.0.50 NIC1
    192.168.1.0 255.255.255.0 192.168.1.1 NIC

    where:
    NIC cofig: IP 192.168.1.1 mask 255.255.255.0
    NIC1 config: IP 192.168.0.50 mask 255.255.255.0 and gateway 192.168.0.1

    and it works fine but only for computers in network 192.168.1 I can ping computers in 192.168.0 and access Internet

    BUT

    when I try to ping 192.168.1.1 form 192.168.0.1 I get request timed out.
    Why?

    Is that makes any sens for you?

    The only way I found to enable communication between 192.168.0.1 and 192.168.1.0 network is to add route:

    route -p add 192.168.1.0 mask 255.255.255.0 192.168.0.50

    but still working on it

    do you have to add the route back as well? or has windows gotten a little smarter?

    that was the manual version.

    Now I figure out that if you add on both routers OSPF in IP Routing then all that process is automatic ( well it takes about 5-10 minutes for the two servers to find each other on the net and update routes).
