Our head office is located in Auckland, New Zealand. We have a new office in London which I would like to attach to our infrastructure (domain, exchange etc). The UK office has an ADSL2+ connection. I have to give them a file server at a minimum but I would like to make it a DC and Exchange server also. They will need to be able to access our network (file servers, SQL servers etc) and normally I would just setup a hardware VPN connection between their office and ours but I would still perfer for their internet traffic not to have to come all the way back to NZ, only the domain traffic.
How would I go about achieving this? I've seen and heard about using RAS and ISA
This also raises the following question
1. Should I put the UK office on a new domain or just on the same domain as our Head Office?
I'm thinking we keep them on the one domain to make life easier for exchange/SQL etc) but i'm not sure as i've seen both types of implementation.
