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.

2b) Right-click on your wired network connection, which is usually named "Ethernet" or "Local Area Connection". After right-clicking, choose Properties.

2c) Click Internet Protocol Version 4 (TCP/IPv4). Then, click Properties.

2d) Click Advanced.

2e) Under the "DNS" tab, check the box next to "Register this connection's addresses in DNS".

NOTE: To use the connection-specific DNS suffix for DNS registration, place a check mark next to "Use this connection's DNS suffix in DNS registration".

2f) Click OK.

3) Attempt to manually force DNS registration.

3a) Run a Command Prompt as administrator.

3b) Type ipconfig /registerdns. Then, press Enter.

OUTCOME

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

NOTE: It can take up to 24 hours to reflect DNS changes.
