501 errors due to Microsoft-WebDAV-MiniRedir/5.1.2600

We have been seeing an increasing number of hits to our website using
the Microsoft-WebDAV-MiniRedir/5.1.2600 user agent. The server returns
a 501 not implemented error. WebDAV is not running on the IIS6
webserver. We are seeing over 3000 entries a day.

here is a record from the logfile:

2006-07-27 04:01:08 PROPFIND /FRAMEWORKS - - 129.44.181.228
Microsoft-WebDAV-MiniRedir/5.1.2600 - - 501 0 0 138

Does anyone know the cause?
Does anyone else see these records in their log files?
I have read that it is from MS-Office applications trying to see if the
file can be saved back to the web. I have also read that Front Page
Clients can be the source.

That's standard webdav redirector request, this is pretty common in today
IIS log file I guess.
The one in your log file belong to XP OS itself, you can use urlscan to
block such request.
