We just acquired a small facility with only 5 computers currently with workgroup. Our HQ currently is with 2003 AD. I've been thinking if we should add one more DC to that facility and have that DC to sync up with my two other DCs in head quarter but would it become an issue since the number of DCs gets bigger and bigger since more acquisitions are coming?
Or have the 5 computers dial up VPN (as needed, not site-to-site) to my HQ to connect the DCs? Any pros / cons. What do you recommend?
