I have classic asp app which I am trying to move from Win2000 Server to Windows Server 2008 x64. Everything seems to be working except file upload feature. It is implemented using FileSystemObject and for the storage server access it uses using mapped drive. I configured app pool to use domain user identity and created the mapping using NET USE under this same user identity. In the app pool settings "Load Profile" setting is true. Still the app does not see the the mapped drive. If I use UNC path directly in test page everything works fine. But to change it throughout the application would be unfeasible. Is there anything else I can do?
