From the Embedded Web Server, click Settings or Configuration.
Click Network/Ports > TCP/IP.
From the TCP/IP section, do the following:
Make sure that the domain name is the same as the one assigned to user workstations.
If you are using a static IP address, then verify the WINS server address and the DNS server address. If a backup DNS server is available, then type the backup DNS server address.
If the printer is located in a different domain, then list the additional domains in the Domain Search Order field. Use commas to separate each domain. If everything is in the same domain, then leave the Domain Search Order field blank.
Apply the changes.
