Upload to a secure website problem

I have a client that can't upload jpg images to a secure manufacturing website. She could upload fine until four weeks ago, and then the problem arose and got progressively worse to the point where the staff member can't upload to a secure image site. When she uses her dongle on her home laptop the system works fine but if she uses her work computer or plugs the same laptop into the work network she can only upload the image once and that’s it. If she clears the cache on the browser on her work Pc she can then upload once and then it stops working.
I have bypassed and ruled out the network switch, the fact that she brought her laptop in means that it can't be a GP or domain policy issue. The only thing i can think of is either DNS, ISP (Zen Internet) or the router (Draytek 2820).
Does anybody have any pointers? Is it the website? Some kind of data filtering on the Draytek or maybe DNS. Can you reinstall DNS on SBS 2011 without messing it up?

If clearing the browser cache lets her upload again...once...then you can pretty easily rule out DNS. And with that out of the way, with the other information you provided, you can rule out SBS. This is an ISP/Draytek problem. My first guess is you have some content filtering occurring at the network edge. Either your edge or the ISP edge, can't really speculate which.

Thanks for yoyr response. Is your thinking that it wouldn't work at all if it was DNS related?Thank you i am onsite now having bought a Drayetk 2830. I am not that familiar with content filtering so i am going to study it now so any tips would be much appreciated. Should i have QoS on? would that help or hinder in general?

It appears it is an ISP upload issue with Zen Internet. i used http://netalyzr.icsi.berkeley.edu/ and then ran it on other systems i looked after. Thanks cgaliher fro the point and the rule outs.
