Some of your users may face problems accessing network resources while using a VPN connection to the corporate network from a workstation running Microsoft Windows Vista.
One reason for this is because a Domain Name System (DNS) suffix cannot be obtained for the TCP/IPv4 address. This happens 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.
To work around this issue, manually configure the DNS suffix for the TCP/IPv4 address in the VPN connection. To do this:
- Click Start, right-click Network, then click Properties.
- Click Manage network connections.
- Right-click the VPN connection that you want to configure, then click Properties.
- If you are prompted to confirm that you want to continue, click Continue.
- In the "This connection uses the following items box" on the Networking tab, click Internet Protocol Version 4 (TCP/IPv4). Then click Properties.
- Click Advanced, then click the DNS tab.
- Specify the DNS suffix for the connection, then click OK three times.
