I was wondering if you guys could help on the best way to set this up...

At the moment i work for a small business using SBS 2003 SP1... using a domain... now we have setup another small business (only 2 users) using a billion router with laptop and graphics machine... now they can vpn in whenever they like to access their emails and files if needed. my question is this the best way, as i dont really want another server machine, and how do i make it so the laptop and graphics machine can talk to each other once they are off vpn???

Thanks

Don't really understand the question. Perhaps you need to draw a quick diagram of how your set up is? However, if you're talking about domain trusts (or any kind of trusts) between 2 SBS 2003 servers/domains you can forget it as it's designed specifically to not be able to do this - believe me I've tried.

If not, post more info because we've got similar SBS 2003 setup here.

Couldn't you just set them static IP's with a default gateway set?
