Supported on :

   At least Microsoft Windows XP Professional or Windows Server 2003 family

Help/Explain Text :

   Determines if a computer performing dynamic registration may register A and PTR resource records with a concatenation of its Computer Name and a connection-specific DNS suffix, in addition to registering these records with a concatenation of its Computer Name and the Primary DNS suffix. Warning: Enabling of this group setting is applied to all the network connections of multihomed computers to which this setting is applied. By default, a DNS client performing dynamic DNS registration registers A and PTR resource records with a concatenation of its Computer Name and the primary DNS suffix. For example, a concatenation of a Computer Name, such as mycomputer, and the primary DNS suffix, such as microsoft.com, would result in mycomputer.microsoft.com. If this setting were enabled, a computer would register A and PTR resource records with its connection-specific DNS suffix in addition to registering A and PTR resource records with the primary DNS suffix. For example, a concatenation of a Computer Name mycomputer and the connection specific DNS suffix VPNconnection would be used when registering A and PTR resource records, resulting in mycomputer.VPNconnection. Notice that if dynamic DNS registration is disabled on a computer to which this setting is applied, then, regardless of this setting's settings, a computer does not attempt dynamic DNS registration of A and PTR records containing a concatenation of its Computer Name and a connection-specific DNS suffix. If dynamic DNS registration is disabled on a specific network connection of a computer to which this setting is applied, then, regardless of this setting's settings, a computer does not attempt dynamic DNS registration of A and PTR records containing a concatenation of its Computer Name and a connection-specific DNS suffix on that network connection. If this setting is disabled, a DNS client does not register A and PTR resource records with its connection-specific DNS suffix. If this setting is not configured, it is not applied to any computers, and computers use their local configuration.
