IDN mapping

Specifies whether the DNS client should convert internationalized domain names (IDNs) to the Nameprep form, a canonical Unicode representation of the string.

If this policy setting is enabled, IDNs are converted to the Nameprep form.

If this policy setting is disabled, or if this policy setting is not configured, IDNs are not converted to the Nameprep form.
