I am trying to use Dreamweaver to Remote Desktop Connect into a computer where a website is hosted. Normal traffic to this server is routed to another domain, but when accessed by IP (it is my understanding) the traffic never hits any sort of nameserver request, and so stays there. This server is set up so that the only way I can access it is RDC. I can connect using an RDC program, but when I attempt to use Dreamweaver, I get a vague error.

The desired action could not be completed because an unexpected client/server communication error occurred.

I have Web URL as http://my.ip.number/directory

And in the settings panel, I have

Host name: my.ip.number
Port: 3388
Host directory: C:\Program Files (x86)\directory/directory
Username: user
Password: •••••••

What could be preventing Dreamweaver form connecting? Thanks!
