When you try to install the Internet Mail Service for Exchange Server 5.5 on a Windows 2000 member server, it does not install, the installation wizard does not continue, and you receive the following error message:

The internet mail service requires DNS domain name to be configured on [server name]. To configure domain name use network control panel on [server name] or select another server.

This error can occur whether or not there is an entry for the domain name suffix on the DNS tab of the Advanced Properties dialog box of the TCP/IP Protocol.


The DNS entry on the Windows 2000 computer is not recognized as a valid domain name entry.


Manually add the DNS suffix to the computer name by following these steps:

  1. In Control Panel, double-click System.

NOTE: Another option is to right-click the My Computer icon on the desktop, and then click Properties. The end result is the same.

  1. Click the Network Identification tab.
  2. Click on the Properties button to display the Identification Changes dialog box.
  3. Click More.
  4. Add the DNS suffix in the Primary DNS Suffix for this Computer box, or example "".
  5. Click OK.
  6. Restart the computer when you are prompted.
  7. Run the Internet Mail Service installation again.


This only applies when the Windows 2000 server is a member of a Microsoft Windows NT 4.0 domain. In a Windows 2000 domain, the full domain name is already implemented and Internet Mail Service installs correctly.
