The only network requirement regarding your VPN is that all local and remote workstations must be able to have full read/write permissions to a Windows Shared folder on the server (C:\FocalPt, usually, but the disk drive can vary.) We do not need this share to be seen using NETBIOS. Using a standard IP address naming convention will work if the VPN is set up properly. For example, this shared folder would be seen on a local or remote workstation by entering this Network Neighborhood address:
\\192.168.1.10\FocalPt
(Please substitute this address with the actual IP address of the server in your network.)
Shared Windows printers are not required to been seen through the VPN, but sharing Windows printers locally at each store can be possible. This way all workstations in one store can print to shared printers, but it is not necessary for those printers in Location A to be seen by workstations in Location B, for example.
Please consult your local networking or computer source for assistance in VPN equipment, setup, installation, and configuration best suited for your remote location needs.
