I've written a file-upload application in VB.net. A web form with a FILE
field that then uploads the file.

Pretty simple.



I'm getting a report from the customer that one particular user can't upload
files as they get an 'invalid path' error.

What's odd is that this is just one person's computer. I can upload just
fine. My customer can too. It's one of their employee's that can't.

As such, this seems like an end-user/client-side issue, but I can't think of
anything specific that would cause this to be an issue. Are there
firewall/virus scanning apps that can interfere with a web-based
file-upload? Any other theories?

Use a program to log all HTTP traffic in that employee (try
http://www.fiddlertool.com/), if his browser works normally (all HTTP
header sent), that is your web app .

What should I be looking for, specifically?
