This might seem rather silly, but I was thinking of opening the log file in sharable read/write mode using a kind of NT service which would start before IIS. That way you could do whatever you want to the file while the NT Service and IIS had it open. But this poses 2 questions 1. Does IIS open the file in lock read/write mode ? If this is the case, then this won't work. 2. What to do when IIS changes log file (at 00:00) ? Well, you could make the NT service create a file just before 00:00 so that IIS would use it also. I'm writing this now, but haven't tested it yet, so probably it wont work. Just my 2 something!

Hmm, I tried it with an IIS4 machine using the IIS log format. After deleting the current log and renaming an old log, new requests were
appended
to the old log, although this format does include the date in each entry.

log
file, but rather create a new one.IIS keeps the log file open, so I don't know of a way to do it without stopping IIS. The easiest way to acccomplish this is to create an AT job that stops IIS, deletes the logs and then restarts IIS. The account thattheAT service runs as probably has permissions to do this. To cause even
more
confusion for the admin, copy an old log and give it the same name as todays' log. Some log types don't show the date in the individual
entries,
but the admin may not notice either way.--------------------------------------------------------------------------
