Just got a new client.
Office in one state (state A)
Office in another state (state B)
state a is main office with Server Enterprise 2003 dc and files using comcast business with static IP going through TZ170 and vpn tunnel to state b
state b is secondary ofice with another Enterprise 2003 Server and is only a file replication server using DSL with static IP also going through TZ170 and vpn tunnel to state a
Loss of internet connections on either end or the dc going down renders state b's office completely useless. They can't even log in and authenticate nor can they still surf the net if it is only down in state a.
File replicaton from state a to state b is run on a nightly basis, but not very reliable using 3rd party software.
What would be the best way to keep both offices up if there was a break in an already not so reliable internet connection or the only dc in state a?
