I Have an asp.net web application that access files on shared folder from remote host,
when the web application is run from vs2008 it retrives the image files and display them.how ever when i deploy the same project in IIS using virtual directory, the application couldn’t access the files on the shared folder it says access denied.

is there any persmission setting i needed to add, I have already add the Asp.net and network service to the project files on the phsical path where the virtual path is pointing too.

    string pic3 = @"\\M37350\temp\GraphicUserImage.jpg";


        FileInfo f = new FileInfo(pic3);


        if (f.Exists)
        {

            Image1.ImageUrl = pic3;
            Image1.Visible = true;
        }

Thanks.

    you’ll need to set the Application Pool’s Identity to a domain account (domain\user) with access to this shared folder, the built-in “Network Service” account doesn’t have access to a remote shared folder.

    To change your App Pool Identity:

    you’ll need to know which Application Pool your website is using by going to the Website properties “Home Directory” tab (Application Pool is the last item)

    Website Properties - Home Directory tab (IIS6)

    Close out the Website properties and under Application Pools in IIS find the corresponding Application Pool, open properties and go to the “Identity” tab to change the user.

    Application Pool Properties - Identity tab (IIS6)
