    Can I have Two SBS2003's on same physical network & subnet, but not same
    domains ?

    I don't need the servers to talk to each other ever.
    I have two businesses on same physical lan and already have one sbs2003

    If I was to install another sbs2003 on same physical lan and subnet (but
    with different domain name) would this work...

    The reason I would like to be able to do this is that I need one client
    machine to be able to log on to either server....

    I realize that I can't do connectcomputer twice, but could access shared
    resources as long as same user details on both servers....

    Hope you can help.

    Kind Regards,

    Phil E

  4. default config is for SBS to run DHCP Server service, if SBS sees another
    DHCP Server on the same network it will shut its own down. In this case the
    two SBSs will randomly (well, actually, there's nothing random about it) be
    supplying DHCP.

    There is interaction between DHCP, DNS and AD, really, turning off DHCPS on
    one box does not address the issue. BUT IT WORKS, mostly.

    A better idea is to run seperate networks

    router -- SBS1 (2 NICs) -- switch -- SBS1 clientPCs
    SBS2 (2 NICs)
    SBS2 client PCs

    if a SBS1 client PC needs to access a resource on the SBS2 network it just
    VPNs in. As the VPN is at the full speed of the router's internal interfaces
    (hopefully 100Mbps or better) they get (mostly, minus VPN overhead) full
    speed access to those resources. Both SBS's are happy because each is
    providing all services it was designed to. Users are happy because they have
    all access they require. Network admin is hapy 'coz he doesn't have wierd
    funky errors happening.

    No actually not.

    I have a very small SBS site 3 users, 3 machines and 2 servers. I used to
    have only one ancient server. So I wanted to upgrade to some new hardware and
    since there is no easy way to migrate and old server to a new server I
    decided to create a new domain (the company also changed name, so I started
    all over :)).

    At the point where the new domain was ready I still had the clients running
    on the old domain without problems, mail, printing, fileshare it all worked
    all on 192.168.x.x ip addresses and the same subnet.

    Then I moved the clients over to the Domain and rebuilded the old server to
    memberserver not running SBS.

  6. It can be done - but I'm not 100% sure about having one machine hit both
    domains . . . what resources does it need to access on each domain?
    Initial thought is use a managed switch to set up two separate vlans - one
    for each domain. Then have your one PC simply VPN into the other SBS to
    access necessary resources . . . much easier setup to maintain and
    administer in the long run . . .

    I only need to use a shared drive from the older sbs 2003 server for Sage
    Network Access. I don't need to use any mail (exchange) or printers etc....

    The client pc will be using its own sbs server for mail and printers...

    If a have a login on the old sbs2003 server, I think I should be able to
    access it, as long as the client pc's username and password are same and so
    can authenticate on both old sbs2003 server and new sbs2003 server.

    What you think ????????
