DNS translating to wrong IP address in Windows


This problem could be caused by one of the following:

  • The host computer is configured for automated IP address assignment with DHCP which has been changed recently.
  • The IP address on the host computer is manually changed but has not been reflected in the DNS server.
  • "Register this connection's address in DNS" option is unchecked in the Network Adapter settings.


1) Find out if the IP address is static or configured for DHCP.

TIP: You may visit the Patterson Support site for the most up-to-date steps on how to do this.

2) Make sure that the computer is enabled for automatic DNS updates.

2a) Open your Start menu. In the search bar, type ncpa.cpl. Then, click the nspa.cpl Control Panel applet or press Enter to open Network Connection settings.

Your DNS network will now route to the correct IP address.
