SYMPTOMS
You establish a virtual private networking (VPN) connection to the corporate network from a computer that is running Windows Vista. When you try to access network resources, you experience the following symptoms:
| • | You cannot access network resources. |
| • | Domain name resolution is not successful. |
Back to the topCAUSE
This issue can occur if one of the following conditions is true:
| • | The computer is not joined to a Microsoft Windows domain. For example, you establish a VPN connection from a home computer to the corporate network. |
| • | The computer is configured to use TCP/IP version 6 (TCP/IPv6). Additionally, TCP/IP version 4 (TCP/IPv4) is not installed on the computer or is not enabled on the VPN connection. |
| • | TCP/IPv4 is installed on the computer. But a Domain Name System (DNS) suffix cannot be obtained for the TCP/IPv4 address. |
This issue occurs because Dynamic Host Configuration Protocol version 6 (DHCPv6) does not support connection-specific DNS suffixes. Therefore, DNS suffixes must be configured by using TCP/IPv4, either manually or automatically.
WORKAROUND
To work around this issue, manually configure the DNS suffix for the TCP/IPv4 address in the VPN connection. To do this, follow these steps:
| 1. | Click Start , right-click Network, and then click Properties. |
| 2. | Click Manage network connections. |
| 3. | Right-click the VPN connection that you want to configure, and then click Properties. |
| 4. |  If you are prompted to confirm that you want to continue, click Continue. |
| 5. | In the This connection uses the following items box on the Networking tab, click Internet Protocol Version 4 (TCP/IPv4), and then click Properties. |
| 6. | Click Advanced, and then click the DNS tab. |
| 7. | Specify the DNS suffix for the connection, and then click OK three times. |
