Software for analyzing IIS logs?

Solution 1:

I used http://www.weblogexpert.com/lite.htm. Is is free and quite good. You install it on Windows like any other program and point it to folder with logs.

There are standard and pro versions which you have to pay for, but lite is also often sufficient.

Solution 2:

I used to run Awffull on a linux box to process all the logs from multiples IIS servers. It was very fast.

Solution 3:

You can query the log files from their storage with the free edition of SpectX. There's a built-in parser for IIS logs and many sample queries listed here:
