Internet Information Services (IIS) on Load Balancer and shared folder for files
In the load balancer setup for windows Internet Information Services (IIS) if shared folder is used for files to upload and download create virtual directory under application folder with alias as Upload(whatever you prefer) and physical path as \\sharedfilefolder\files$\AppFiles\ where files is the shared folder on sharedfilefolder and AppFiles is subfolder in the files folder Have the same setup on each server and the application works fine with upload and download of files from load balancer URL.
