Microsoft ISA 2004 and Access denied

Problem

When connecting through a Microsoft ISA 2004 server, the FTP client has read only access to files and folders. Uploading, renaming, or deleting a file or folder is not possible. The FTP server replies with the following error: 

550 Access denied.

Solution

Microsoft ISA 2004 server (acts as Firewall) default settings only allow read access (list and download).

To change these settings open ISA management -> Select Firewall policy -> Web Access -> Protocol -> Filtering ->Configure FTP. On this page remove the check mark from the "Read Only" option.
