I have a Windows Server 2008 SP2 with these Roles installed:
- File server
- Network Policy and Access Server / Routing and Remote Access
- Network Policy and Access Server / NPS
The VPN connection is connecting, but it is not possible to share a Network folder situated on this server. Shares on other servers in the same network work as expected.
Trying to map a network share through Windows Explorer gives the following error:
The mapped network drive could not be created because the following error has occurred:
The specified network name is no longer available.
net view \\rras-server gives the following error, while net view \\other-servers works and shows the shared folders available.
Error 53: The network path was not found.
I tried to troubleshot and found these indications:
- Ping works on server name and IP address
- Nslookup shows that DNS lookup is working as it should
- Disabling the firewall on the server does not help
- The same problem occurs with Windows XP and Windows 7
Where could be the problem ?
The following behavior shows when the client computer is on the local network, but VPN is connected (The advanced setting Use default gateway on remote network is not checked):
In Windows Exporer, the network share shows with a red cross, and when I click on it, one of the following errors occurs:
An error has occurred while connecting [drive letter]: to [share name]
The parameter is incorrect
An error has occurred while connecting [drive letter]: to [share name]
The specified network name is no longer available
On the other hand, when I open Eplorer with the VPN disconnected, and then connect the VPN, the navigation in the network share continues to work.
My final solution (I know this is not really an acceptable answer):
I installed the RRAS role on an other server that does not have file shares. Since then everything is OK.
