WinDNSLogAnalyser   -  Analyse your Windows DNS log

Windows DNS Log Analyser is a free utility that will read and analyse your Windows Server (2000, 2003, 2008) DNS Log.

Your DNS log holds the answer to many network problems, and using this tool can help you track down problems on your network, even if those problems are silent, and help you optimise your home or corporate network. For example:

  • Malware (botnets, adware, spyware, mailers etc) will often use DNS to lookup target and home addresses. The analyser will quickly show you the most active client, and requested host, enabling you to detect unusual activity.
  • Every website that is browsed requires a DNS query. The analyser can show you which websites are the most commonly requested without the need to install client software, or use a proxy server.
  • Like it or not, IPv6 is coming, and even if you haven't specifically configured IPv6 anywhere, the analyser can show you what AAAA requests are being made, and by which clients.
  • The analyser will help you track down poorly configured applications and clients that are making requests that the DNS server cannot resolve.
  • Find out which hosts are being refused SOA requests
  • Filter your log by request direction (Snd/Rcv), by response (SERVFAIL, NXDOMAIN, REFUSED, NOERROR), or by text string in the query
