January 7, 2013 at 13:06:06
Specs: small business server 2003, 2.2 / 8gb

My company bought another company and moved them into our building. the company moved in but are on an entirely different network all together. wired seperatly, different domains.
what i would like to do is be able to have them communicate with each other. have users on company A be able to use printers on company B's side of the network. IS THIS POSSIBLE.

that was the first thing i did, google is my friend.. but i've still not gotten a grasp on it.. the domains are not connected physically anywhere. from domain B i can ping Domain A and get a response, but from domain A to Domain B, nothing. the physical computers are about 2 feet apart but do not intertwine in any way. this building is 1200 feet long. domain B uses 3 switches to get to the other end of the building, the first switch is directly under a switch belonging to domain A, on the same rack.
maybe i need to do more reading but jeeshhh...

Sorry about that. I just noticed you listed Small Business Servers. No trusts with SBS. Takes a nonSBS server to do trusts.

@ JEFFERYLACKEY , it is possible. First of all you will need to draw a communicable IP convention and subnet.
Example, Network Company A router IP can be 182.16.10.1 and Network router B IP can be 182.16.20.1 and both subnet to be 255.255.255.0 then give this range of IP to hosts under each router's network. Mean all hosts under company A would have their range starting from 182.16.10.2 and under company B 182.16.20.2 and so on with same subnet IP and each host with their respective router IP address as default IP for accessing resources.

Then you will need to have admin right on the two domain through you can be granting access to authentication prompting windows security.

Map to any side or PC on the networks preferably by IP address and authenticate windows security and connect to either network shared pinters, folders or drives.
Example on username authentication; domain name\username and password.

Send update in case there is any issue.

Thanks.

that solution might have worked if i had set up the network from the start.
all of our ip addresses are set up manually. i would have to change all settings in our 4 routers, and over 60 computers, 4 printers... don't think my boss will authorize that kind of alteration. i'm now looking into a way to put the networked computer outside our router for access from any computer with the proper user name and password..
google is my friend but he sure hurts my eyes after a while.

Azedas are your seriously saying you can establish a trust between two SBS forests?

You are clear in the difference between a forest and a domain?

Trusts have nothing to do with routing except routing is the underlying foundation.
Having two subnets have nothing to do with gaining domain access.

Jefferylackey you can spend time googling but it will be to no avail. I would suggest you start planing a migration from the SBS to a dual DC setup with 2008/2010

@ wanderer , this is what I had faced as a problem and find solution. If @ JEFFERYLACKEY , can restructure the networks as I discussed resources can be well managed over the two domains.


Thanks.

azedas101 you are clear we are talking about two Small Business Servers which do not support trusts?

" Windows Small Business Server cannot trust any other domains. It cannot have any child domains "

http://en.wikipedia.org/wiki/Window...

How would two subnets override this limitation of having trusts between these two servers?

Okay. In respect to wanderer last post on trust with Small Business Server which are servers I am not used to. I would advise trying my above guide and if it does not work then we can make more research on the issue or if server migration can be applied.

Thanks.

azedas101

It would seem you're not understanding the question. Let me reiterate. The OP wants to have two separate SBS based domains share resources:

"what i would like to do is be able to have them communicate with each other. have users on company A be able to use printers on company B's side of the network"

Connecting them across the network is not the issue here and is one that's quite simply resolved. If all you wanted was network connectivity between the two, you could make them one single shared subnet which is a whole lot easier than two separate subnets as it doesn't require routing between the two domains.

But, that's not the point.

In order to share resources, one must have trusts which as wanderer has pointed out, isn't possible with two SBS based domains.

Now clear better but in my previous post only a subnet is advised.
Let me see how I can still be of help. The only challenge on this is I have no access to SBS since working but I promise to do some home works and get back.

Thanks.

Check the above to establish trust between two forest/domain.

As per wanderer in response #8

" Windows Small Business Server cannot trust any other domains. It cannot have any child domains "

Feel free to confirm by clicking on the link he provided in the aforementioned response and reading it through.

While we appreciate you're trying to help. Telling someone to establish trusts, and providing links to info on how to establish trusts, isn't helping when you cannot establish trusts between SBS based domains and the OP is talking about SBS domains.
