I've set up a single hosted server to use as a development environment for a web-based application. The web app is served up fine on port 80, however I'm struggling to get my VPN to behave how I'd expect so the developers don't have the access they require.

The VPN connects fine and I can access the back-end database (SQL Server) which resides on the server with the client tools from the laptops. However they cannot access any shared folders.

The server's local IP address is 10.x.x.x, and I've assigned a static IP address pool to RRAS (of 192.168.100.1 - 20). The clients pick up a valid IP Address (i.e. 192.168.100.9) when they connect. There is no name resolution setup, DNS or WINS. When connected via VPN the clients can ping the server (192.168.100.1) by IP Address, but cannot map a drive to a shared folder (net use * \\192.168.100.1\xxxxx) - I get 'System error 53 has occurred. The network path was not found.' I don't understand why I can ping by the ip, but not map by it.

Some details:

• Server OS is Windows 2008 (Datacenter)
• VPN is SSTP using RRAS
• Clients are all Windows 7
• I've tried temporarily disabling the firewalls

So, why can we not access the file system when everything else (ping, RDP, SQL Server clients tools) works?

Thanks for your help
