Hey,
I just ran that code and it didn't work. I made a copy of the log file and put it on my desktop so I wasn't messing with the real one when I tested, and the lines with that IP are still there. Any ideas? Here's the code with the small change for location.
/Apache.Strip { var %LogFile = “C:\Documents and Settings\Owner\Desktop\access.log” filter -ffxc %LogFile %LogFile 192.168.1.97*}
