NoteHKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\<interface-name>
| Data type | Range | Default value |
|---|---|---|
| REG_SZ | Domain name | (There is no default value for this entry. The value is configured by DHCP.) |
Specifies the Domain Name System (DNS) domain name of the interface, as provided by DHCP.
The DNS domain name is determined by three entries, DhcpDomain, which is configured by DHCP, and by Domain, which you can configure.
If these entries contain valid values, the user-configured value, Domain, takes precedence over the value of DhcpDomain.
Note
The DHCP client service adds this entry to the registry when the service is enabled. Do not change the value of this entry.
Tip
This entry is associated with a DHCP option. Configuration data for DHCP options is stored in each HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Dhcp\Parameters\Options\ <Option#> subkey. The path to this entry is stored in the value of RegLocation in the associated <Option#> subkey.
To find the DHCP option associated with this entry, use Regedit.exe. From the Edit menu, click Find, and enter the following text: SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\?\DhcpDomain and select only the Data checkbox.
