Hello Peter, You seem to be very experienced with these things so hopefully you can shed some further light on this. In my case, the server requires a digital certificate for access. I have installed that digital certificate on my client, so when I try to access the resources (a folder) on the server using IE, a small window pops-up telling me that the "Web site I want to view requests identification". I am prompted to select a digital certificate and upon selecting the one I installed I gain access to the remote folder. Now, as you pointed out, the WebClient.DownloadFile method will not take me to the UI where I need to select the digital certificate. I fact I don't even need this step. I am trying to automate the daily download of a file and there should be no human input in the process. I guess I need to somehow indicate that I want to use the respective digital certificate when I create the web session. Is there a way this can be achieved with the WebClient class or I need to look at a different class / approach?

As long as the server's cert is from a well-known Authority you shouldn't have a problem with an https url. If the cert isn't from a well-known Authority and the Authority isn't in the Trusted Authorities list or the cert isn't in the Trusted Publishers list you'll have to added in advance. WebClient has no UI, so it can't ask the user if the unknown cert is acceptable like IE does, so it just fails. =================================== This list is hosted by DevelopMentor® http://www.develop.com View archives and manage your subscription(s) at http://discuss.develop.com =================================== This list is hosted by DevelopMentor® http://www.develop.com View archives and manage your subscription(s) at http://discuss.develop.com
