To configure TCP/IP to use DNS

  1. Open Network and Dial-up Connections.
  2. Right-click the network connection you want to configure, and then click Properties.
  3. On the General tab (for a local area connection) or the Networking tab (all other connections), click Internet Protocol (TCP/IP), and then click Properties.
  4. If you want to obtain DNS server addresses from a DHCP server, click Obtain DNS server address automatically.
  5. If you want to manually configure DNS server addresses, click Use the following DNS server addresses, and in Preferred DNS server and Alternate DNS server, type the preferred DNS server and alternate DNS server IP addresses.
  6. To configure advanced DNS properties, click Advanced, click the DNS tab, and do one or more of the following:
    • To configure an additional DNS server IP address:
      1. Under DNS server addresses, in order of use, click Add.
      2. In DNS server, type the IP address of the DNS server, and then click Add.
    • To modify the resolution behavior for unqualified DNS names, do the following:
      • To resolve an unqualified name by appending the primary DNS suffix and the DNS suffix of each connection (if configured), click Append primary and connection specific DNS suffixes. If you also want to search the parent suffixes of the primary DNS suffix up to the second level domain, select the Append parent suffixes of the primary DNS suffix check box.
      • To resolve an unqualified name by appending the suffixes from a list of configured suffixes, click Append these DNS suffixes (in order), and then click Add to add suffixes to the list.
    • To configure a connection-specific DNS suffix (local area connection only), type the DNS suffix in DNS suffix for this connection.
    • To modify DNS dynamic update behavior (local area connection only), do the following:
      • To use a DNS dynamic update to register the IP addresses of this connection and the primary domain name of the computer, select the Register this connection's addresses in DNS check box. This option is enabled by default. The primary domain name of the computer is the primary DNS suffix appended to the computer name and can be viewed as the full computer name on the Network Identification tab (available in System in Control Panel).
      • To use a DNS dynamic update to register the IP addresses and the connection-specific domain name of this connection, select the Use this connection's DNS suffix in DNS registration check box. This option is disabled by default. The connection-specific domain name of this connection is the DNS suffix for this connection appended to the computer name.

Notes

  • To open Network and Dial-up Connections, click Start, point to Settings, and then click Network and Dial-up Connections.
  • You must be logged on as an administrator or a member of the Administrators group in order to complete this procedure.
  • To completely disable DNS dynamic update for all names on the computer, clear the Register this connection's addresses in DNS and Use this connection's DNS suffix in DNS registration check boxes for all connections in Network and Dial-up Connections.
