Managing the many logs generated in a Windows environment is a time-consuming—though necessary—part of systems administration. Each workstation, member server, and domain controller (DC) has a Security, Application, and System log, all of which contain valuable security and system information. Depending on your environment and which Windows components you use, you might also have logs generated by Internet Authentication Service (IAS), Microsoft IIS, RRAS, and URLScan, not to mention the logs generated by application servers such as Microsoft Exchange Server and Microsoft SQL Server. Each of these logs has a different format and structure as well as a hefty amount of noise—activity that you must filter out before you can find important events. Wouldn't it be great to have a tool that could read and execute SQL-like queries against any type
of log? This dream is reality in the form of LogParser, a command-line utility that you can use with Windows 2000 and later. LogParser gives you the data-mining power of a SQL database such as Microsoft Access, and you can use the tool to automatically process the megabytes of data that your network's diverse logs generate every day. As I write this article, the most recent version of the tool, LogParser 2.1, is available for download as part of the IIS 6.0 Resource Kit Tools (http://www.microsoft.com/downloads/details.aspx?familyid=56fc92ee-a71a-4c73-b628-ade629c89499&
