and here:

I have done the following:

1. Installed FTP services in IIS
2. Set up an FTP site in IIS pointing to the directory where I want the files to be accessed.
3. Configured FTP firewall support at the server level using ports 41000-41099 and external IP address of my elastic IP

4. Run the following:

   netsh advfirewall firewall add rule name=FTP_Service action=allow service=ftpsvc protocol=TCP dir=in netsh advfirewall set global StatefulFTP disable 

5. Added the necessary inbound rules in the instances security group for ports 41000-41099 and 21

6. Restarted the FTP service.

However In FileZilla I am still unable to connect using the elastic IP and my Administrator login credentials. I get this error:

Status: Connecting to Elastic IP... Status: Connection established, waiting for welcome message... Error: Connection closed by server Error: Could not connect to server Status: Waiting to retry... Status: Connecting to Elastic IP... Status: Connection established, waiting for welcome message... Error: Connection closed by server Error: Could not connect to server

Have you tried to open port 21 by Security Group settings? (AWS Security Group settings)
