Controlling DNS

Controls DNS-related local settings. The administrator can specify a DNS server to prevent PCs with the agent installed from arbitrarily setting DNS. It is also possible to add/remove hosts file entries that can bypass DNS.

  • Enforces settings to the administrator-specified DNS server, ensuring compliance with corporate internal DNS regulations.
  • Allows removal of specific entries if the hosts file is corrupted due to a security incident.
