How to modify the resolution behavior for unqualified DNS names

To modify the resolution behavior for unqualified DNS names, follow these steps:

1. To resolve an unqualified name by appending the primary DNS suffix and the DNS suffix of each connection, click Append primary and connection specific DNS suffixes. To do this, each connection must be configured. If you also want to search the parent suffixes of the primary DNS suffix up to the second-level domain, click to select the Append parent suffixes of the primary DNS suffix check box.
2. 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.
3. To configure a connection-specific DNS suffix, type the DNS suffix in the DNS suffix for this connection box.

How to modify DNS dynamic update behavior

To modify DNS dynamic update behavior, use any of the following methods:

• 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. By default, this check box is not selected. The primary domain name of the computer is the primary DNS suffix appended to the computer name. To view this domain name and DNS suffix together as the full computer name, click Start, click Control Panel, click Performance and Maintenance, click System, and then click the Computer Name tab.
• 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. By default, this check box is not selected. The connection-specific domain name of this connection is the DNS suffix for this connection appended to the computer name.

Troubleshooting

To disable DNS dynamic update for all names on the computer, clear the Register this connection's addresses in DNS and the Use this connection's DNS suffix in DNS registration check boxes on the DNS tab for all connections in Network Connections.

Note You must be logged on as an administrator or as a member of the Administrators group to use this procedure. If your computer is connected to a network, network policy settings may also prevent you from using this procedure.
