I saw some older posts here about the issue but would like to ask for some news maybe available.

Anyone have some idea what this really is as it seems a bunch of this. Is it M$ Frontpage on XP crap horsing arround the Net or is this a more serious treat?

Thank you in advance!

Thanks fiestaGirl!

But it does not make much sense to me as this is over a year ago that I'm too readed about this leak in M$ WebDav.

I'm running an Apache/2 at Solaris 9 Sparc and have a real bunch of this requests with "Microsoft-WebDAV-MiniRedir/5.1.2600" the whole day. So I think there must be something else behind as someone looking for IIS leak at an Solaris Apache.
