iis security : IIS 6 Logging

Is there any way to prevent IIS 6 to log certain requests, such as the worm
virus attempts:

2003-07-06 04:36:28 W3SVC1 MILLENNIA 192.168.1.101 GET /scripts/root.exe
/c+dir 80 - 66.56.41.105 HTTP/1.0 - - www 404 0 64 0 72 1361
2003-07-06 04:36:32 W3SVC1 MILLENNIA 192.168.1.101 GET /MSADC/root.exe
/c+dir 80 - 66.56.41.105 HTTP/1.0 - - www 404 0 64 0 70 1622

I understand that those are "not found" benign messages but they are filling
up my IIS logs and affecting the way the log analyzers interpret the
results. I tried the UrlScan 2.5 but it doesn't prevent these messages to be
logged. Ideally, I would like these rejected before the request reaches IIS.

I think the point is that we became spoiled with URLscan on IIS 5
where these junk attempts would get filtered over to the URLscan
log, keeping the IIS log more meaningful.
AFAIK all that can be done is to post-process the IIS log to grep
out the lines of interest.

I recommend you take a look at AQTRONIX WebKnight.
http://www.aqtronix.com/webknight/

WebKnight does exactly what urlscan does and much more like
keeping the blocked requests out of your IIS log files
(WebKnight logs them to a separate file).

Why so ? such information give you the info on any attacks.
and I don't think you can turn it off, unless you disable
entire logging in IIS.

Yes, most log analyzer tools allow to filters
unwanted entry before processing.
