This article describes how to change the IP addresses of your Windows Essential Business Server (EBS) computers. You can use the Change IP Address Settings Wizard to change the IP address settings of a network adapter on the Windows EBS Management Server, Security Server, or Messaging Server. When you change the IP address settings on one server, the wizard reconfigures connections to the other two servers to keep your network functioning properly. For more information on all the settings that are changed please see http://technet.microsoft.com/en-us/library/d37f87de-5601-4a9f-9487-a79779933100.
