Error: Access denied
It is very common experience to every developer when he/she host a file uploader page. Interestingly developer does not face this error in development PC.
The main reason of this problem is security issue of the host computer. Host pc does not allow write operation of IU or Guest user. But IU and guest user need write access of upload folder in host pc.
the solution if not very standard considering security. follow the below steps,
1. enable write access of virtual directory of the page using IIS(default value of write access is unchecked )
2. Right write click uploading folder of the site. In the security tab provide write access to Users, Internet Guest Account.
The main disadvantage of this technique is the security. Write access of IU user some time vulnerable. so, alternatively your can use database to store file instead of file system.
