Situation: Company A purchased Company B. Offices are 40 miles apart. There are about 10 employees in each office. We want to have everyone be able to access all network resources independent of location.
Company A - Windows 2008 Server domain controllers, Win XP, and Windows 7 workstations. Company B - Windows 2003 Server domain controllers, Win XP, and Windows 7 workstations.
Company A, has T1 connection to internet, and Cisco ASA 5505 firewall. Will add 2nd T1 line shortly. Company B, has 25x3Mbs connection to internet, and WatchGuard firewall.
Company A and B have different subnet addresses on their internal LAN.
How should this be done?
