Aldo I would still very much like you to take a look (to confirm that it
is not Samba causing the problem), I'm affraid I already know what the
problem is.

We are using DFS (distributed file system) to connect to our Samba
server. Now when I change the path from DFS to a standard UNC path and
refresh the site... The error is gone...

So I think I'm going to call M$ about this one. I already searched
google, but that didn't give me any leads...

Though I do have another question! Can you tell me why changing the
'change notify timeout' to say 5 seconds isn't a good idea? At least,
that's what I read around the internet (google again ;). We need this
setting to be something like 5 seconds for our setup to work.
