Reconfigure client computers and existing servers to use Windows Essential Business Server for DNS

  • Article

Important

Do not continue if you encountered issues that you could not fix in the previous procedures.

You must configure computers in your environment to start using the Management Server to service DNS requests. For statically addressed computers, manually configure each network adapter’s TCP/IP properties to use the following DNS servers:

  • Preferred DNS server: the IP address of the Management Server

  • Alternate DNS server: the IP address of the Messaging Server

Do not use the following servers:

  • Your old DNS server

  • DNS servers outside of your organization

  • Your Internet service provider’s DNS servers

Follow these instructions to set the network adapter’s TCP/IP properties for a statically addressed computer:

To set the network adapter’s TCP/IP properties for a statically addressed computer

  1. In Control Panel, open Network Connections.

  2. Right-click the connection to your organization’s network, and then click Properties.

  3. Depending on the Windows operating system on the client computer, click Internet Protocol (TCP/IP) or Internet Protocol Version 4 (TCP/IPv4), and then click Properties.

  4. On the General tab, verify that Use the following DNS server addresses is selected, and then type the IP addresses into the Preferred DNS server and Alternate DNS server text boxes.

Follow these steps to change your DHCP settings for dynamically addressed computers (computers that obtain their IP addresses automatically through DHCP).

Note

These steps assume that your DHCP server is running a Windows Server operating system. If it is not, consult the documentation for your DHCP server to determine how to change the DNS settings that your DHCP server provides.

To change DHCP settings for dynamically addressed computers

  1. Log on to your DHCP server as domain administrator.

  2. To open the DHCP console, click Start, click Administrative Tools, and then click DHCP.

  3. In the left pane, right-click Server Options, and then click Configure Options.

  4. In the Server Options dialog box, on the General tab, click 006 DNS Servers, and then type the IP addresses for your Management Server and Messaging Server (in that order). There should be no additional IP addresses specified. Click OK until all the dialog boxes are closed.

  5. For each scope in the left pane, click Scope Options, and then verify that the settings in the right pane for 006 DNS Servers match what you just entered. If they do not, you can override the option settings as follows:

    1. In Scope Options, right-click the 006 DNS Servers setting that does not match, click Delete, and then click Yes in the confirmation box.

    2. Right-click the right pane, and then click Refresh. The value that appears should match what you configured in Server Options.

  6. Restart the DHCP Server service. (In the left pane, right-click the node that represents your DHCP server, click All Tasks, and then click Restart.)

Note

You need to perform the DHCP migration later. For instructions about how to migrate the DHCP workload to Windows EBS, see the Microsoft Web site (https://go.microsoft.com/fwlink/?LinkId=95815).
