The software implements a DNS Server for all Windows platforms.
The server can run as Primary or Backup name server and supports dynamic DNS updates based on RFC 2136.
The server operates as a so called "recursive DNS forwarder" with caching. Requests for non local domains are answered from the cache or forwarded to external nameservers.

in Version 1.5:
The installer contains the 32bit software and native x64 versions of the server programs.

For Windows 200x/XP/Vista/7 the DNS server is implemented as native service for background operation. A Control Panel applet provides interactive access to the service.

For Windows 9x/ME the DNS Server is implemented as application and can run as service with nobody logged in.

The software is shareware.
