Description:  

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.

Supported on: At least Windows XP Professional or Windows Server 2003 family.
