Yup. Happens all the time.

It has been the cause of no-end of helpdesk reports to our IS staff over the
years.

As usual it's to do with M$ IE talking to Web servers. Due to "integration"
between IE and M$ Office, IE tends to change how it talks to Web servers
when it:

a> notices the URL you are downloading is an M$ Office doc
b> time of the month

At that stage, IE decides to see if it can *EDIT* the document from afar. It
will try an assortment of methods, including FrontPage (see: sid:968,1288
and the other 30+ alerts) and WebDAV. It tries to lock the file to see if
WebDAV is supported. Typically this fails, at which stage IE fails-back to
standard behaviour (good), or gives some damn weird error to the user (hense
the calls to our IS helpdesk.)

Microsoft: need I say more?
