Uploading files to file server using webclient class

Question

Currently I have an application that receives an uploaded file from my web application  I now need to transfer that file to a file server which happens to be located on the same network  however this might not always be the case    I was attempting to use the webclient class in C   NET       string filePath    C   test  564 flv       try               WebClient client   new WebClient             NetworkCredential nc   new NetworkCredential uName  password            Uri addy   new Uri      192 168 1 28  Files  test flv            client Credentials   nc          byte   arrReturn   client UploadFile addy  filePath           Console WriteLine arrReturn ToString               catch  Exception ex                Console WriteLine ex Message           The machine located at 192 168 1 28 is a file server and has a share c  Files  As of right now I am receiving an error of Login failed bad user name or password  but I can open explorer and type in that path login successfully  I can also login using remote desktop  so I know the user account works   Any ideas on this error  Is it possible to transfer a file directly like that  With the webclient class or maybe some other class

when you manually open the IP address  via the RUN command or mapping a network drive   your PC will send your credentials over the pipe and the file server will receive authorization from the DC   When ASP Net tries  then it is going to try to use the IIS worker user  unless impersonation is turned on which will list a few other issues    Traditionally  the IIS worker user does not have authorization to work across servers  or even in other folders on the web server
