We have configured VPN in windows 2008 server. Two NIC one public and a loopback adapter with private IP 192.168.2.200.
We can connect via VPN for any users in system and can check the shares \192.168.2.200, however If we try to connect drive \192.168.2.200\c$ for any users other than administrator it gives 'Logon unsuccessful' message. Only administrator can connect.
Now we have shared the C drive to gain access to files for the users connecting to system. I have checked with Firewall and other network and share settings in the server which is fine.
Any idea will be highly appreciated!.
Thats how its supposed to be. Shares with a $ after it are administrative shares and thus you have to be an administrator to get to it.
Edit: After verifying pauskas comment it would appear that only the default shares like that are administrator equivalent only.
