Pb with Webclient object since Framework 3.0 installed. need help !!

[Xavier Mauclaire]

Hi

I've got a piece of code using the webclient object (see below). This
function was working until i installed the . Net 3.0 on my computer. This
code run withs the version 2.0 of the dotnet Framework.

After this installation, the OpenRead functiuon generate an error. "Can't
open a session, wring username or password". Or Creadentials informations
are good.

This code will works if i connect to the shared network with the explorer
before using it. I don't understand !!

The shared folder is located on a linux server.

Thanks in advance
