SYMPTOMS

Client computers that use Remote Access Services (RAS) or a Virtual Private Network (VPN) to log on to a Windows 2000 domain controller may receive a DNS server address of 127.0.0.1. The clients may be unable to resolve host names to TCP/IP addresses, and they may receive error messages similar to the following examples:
  • Bad IP address
  • System error 53 has occurred.
    The network path was not found
  • Unknown host

CAUSE

This behavior can occur if the Windows 2000 domain controller did not have any DNS server addresses listed in TCP/IP properties when it was promoted to a domain controller.

RESOLUTION

To resolve this issue, either follow the server steps to fix this on the server that is running Windows 2000 Routing and Remote Access or use the Client steps if you do not have access to the RRAS server.

On the Server

  1. Right-click My Network Places, and then click Properties.
  2. Right-click the Local Area Connection (LAN) icon for the network card, and then click Properties.
  3. In the Components checked are used by this connection area, double-click Internet Protocol (TCP/IP).
  4. Change the Preferred DNS server value from 127.0.0.1 to the TCP/IP address being used for this network card, and then click OK.
  5. Have the RAS client disconnect and reconnect.

On the Client

Microsoft Windows NT 4.0 or Windows 2000

Statically configure the DNS server addresses in the phone book entry.

Microsoft Windows 95 or Microsoft Windows 98

Windows 95/98 clients automatically use the DNS and Windows Internet Naming service (WINS) server addresses that the RAS server assigns, even if the phone book entry at the client computer is configured with statically assigned DNS and WINS server addresses.
