Just changed web hosting providers.

I'm using Contribute 4. This problem only seems to happen when I'm linking a
new file from our network (ie PDF file) into a Webpage to be published with the
Webpage.

I link the file, hit publish, get "Access Denied" and the Webpage is in edit
mode. But if I go browse to the Webpage, the file successfully published and
uploaded the PDF file. So it's like it's throwing the error directly after
publishing the PDF file. I then just go into my draft Webpage and cancel the
draft. Sounds like a weird permissions problem. Anybody ever have this happen?
