Providing a Realm Name

Updated: April 8, 2009

Applies To: Windows 7, Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2, Windows Server 2008, Windows Server 2008 Foundation, Windows Server 2008 R2, Windows Server 2012, Windows Vista

Realm names are used for network routing and authentication. They provide the identification necessary to forward authentication requests to the server that holds the user's credentials. Realm information is only used for dial-up connections.

Using the CMAK wizard, you can specify a realm user-name prefix (such as Awesome/) or suffix (such as @Awesome) to be added to the user name that a user enters when connecting to your service. The realm name must include any separator characters, such as @ or /, if required. If you specify the realm, users do not have to provide it themselves because Connection Manager automatically places the realm name before or after the user's name so that the user does not have to understand network routing in order to log on.

If your service uses multiple networks or ISPs for access, you need to provide different realm information for each. In this case, create service profiles for each of the networks and then merge them together in a top-level profile.

noteNote
If the top-level profile contains realm information, it will take precedence over the information in the component profiles. For more information on merging profiles to incorporate multiple realms, see Merging Phone Books and Other Features from Existing Connection Profiles.

Network Policy Service (in Windows Server 2008 and Windows Server 2008 R2 and Internet Authentication Service (in Windows Server 2003) support the use of realm names for remote authentication. You can use the realm name as authentication routing information for remote roaming users (users who travel and connect through different Internet access points). When the user connects through a network access server, the server sends the realm name, the user name, and the user password to the authentication server.
