Hoping to get some feedback from anyone who may be doing or have tried this before. I’ve got a central office and 6 remote offices running cisco hardware based vpn routers. The links seam very stable. We’ve been running in a workgroup design up to this point. Most remote offices run a fractional T1 (256k-384k), some run DSL. Main office runs DSL at 3.0M down / 512K up. We want to move to a domain model (we currently only run a domain within the main office). Is it possible to authenticate over such a link? I’m not even going to try and store user documents on the server as I’m sure the links will be to slow. But if we could authenticate to the domain I could run several services I can’t run now. One example amoung many is that I could run backups from their local machines to a NAS device then to tape. Any thoughts on performance, or is this a theoretical pipe dream?
