I work at a manufacturing company w/ about 30 users using XP pro clients on a Win2k3 server. We have a DSL connectiion and a Sonic Wall TZ 170 router. My company is going to buy a second facility 100 miles away and wants to know how we are going to incorporate the two networks. I am not sure how to go about this. If I set up site to site VPN will the networks appear as one network? Also i will need a second server at the new site, correct? What do I need to do in Win2k3 to configure all this ( as far as active directory and DNS)?Can someone give me a run down based on this information of a feasible way of going about this?
