Two SBS 2003 servers sharing one application server

    We have a company with one sbs 2003 server. The company is going to split
    into two seperate companies although still in the same physical building. One
    company (A) will continue to use the existing sbs (server A). The new company
    (B) will get its own sbs server (server B). The two will share a single
    Internet circuit but will be seperated by a router and each have its own
    switch and IP addressing for itself and its workstations. The issue is how to
    have each server (A and B) and its workstations access a single application
    server (C) but not each other? Where would the app server (C) need to be? Is
    it a member of one of the domains and somehow the other domain can access it?
    Or is it in its own domain and both servers are able to access it? Any ideas
    on a way to accomplish this? Thanks

  2. Hi Dave:

    This is going to take a fair amount of trust on both sides. It can be a
    member server on domain1, thereby allowing access with the domain logon. It
    becomes a licensing issue for domain2, as they will still need accounts and
    licenses for domain1, but will be challenged for their credentials every
    time they access the member server of another domain.

    You could even have the Domain2 users access the member server with RWW, so
    long as they have an account on Domain1, but of course it would then have to
    be a TS as well, and require TS licenses for those that did this.

    Without knowing the details of the split, I might keep one SBS domain and
    give the second set of users a different email address and forget about
    separate SBS boxes.

  3. While we do need more info, I'm thinking a Terminal Server behind its own
    router, accessed by each SBS domain.

    Also, with two SBS servers sharing one Internet connection, there's going to
    be conflicts with ports. Like:

    25... email
    443... SSL
    4125... RWW Proxy
    1723... VPN
    3389... RDP to server

    This could limit remote access (by users and for remote administration of
    the servers). A separate Internet connection for each domain would be

  4. Merv is right. Regarding the two SBS systems, we just had a long thread
    about that, the conclusion reached is that there should be at least two
    public ip addresses and two routers, one for each public IP to forward the
    required ports to each SBS server, assuming you continue to plan along these

    Please post the resolution to your
    issue so that others may benefit.

    thanks for the response. The main reason for the two sbs boxes is that each
    company will need to be completely independent of the the other. Each needs
    their own Exchange and Sharepoint and user accounts limited to their assigned
    server. The common thread will be accessing the application server for both
    companies while staying independent of each other. At some point in the
    future the two companies will move to separate buildings and have their own
    Internet circuits. They are trying to pre-stage the split while still in the
    same building. Do you need any other information?

    You are suggesting that the application server become a stand alone server
    acting as a terminal server and the two domains making a ts connection to it.
    But that would require a new internet connection for that server correct?
