Hello Experts,
            Here is the problem. I have an office in City A and office in City B. In Office A my server is assigning IP's 192.168.50.100 - 192.168.50.148 . At Office B my router is assigning IP 192.168.50.2 - 192.168.50.50. My server is a RAS server as well. I have created 3 machines at office B to connect VIA VPN to Office A. My Server assigns IP 192.168.50.151 - 192.168.50.160 for VPN. When I connect VPN from B to A, I can no longer see my local network printer at office B. What can I do to fix this. It seems to me since A and B are on the same network I should be able to see the printer

You have 2 problems. You don't know about the second yet. <G>

The VPN client has built-in safety feature to block all traffic from your local network, from accessing the remote VPN. This is a safety feature. To change that and allow connection to local and remote networks, accepting any risks, go to:
Control panel | network connections |  right click on the VPN virtual adapter and choose properties | networking | TCP/IP -properties | advanced | General | un-check "use default remote gateway"

However, once you do this, because the local and remote networks are on the same subnet it will 'break' the VPN. The router will have access to both networks and not know where to send the 192.168.50.0 packes, the local or remote office. As a result VPN's require both sites to use different subnets. This is critical. You will need to change one or the other sites to 192.168.60.xx or something similar. As for connecting to both networks it will appear seamless even with 2 different subnets as the VPN/routers will automatically look after routing the packets.
