“530 Valid hostname is expected.” when connecting to FTP site in IIS

Question

I have created a FTP site in IIS where I configured a host header. I know that to connect to the FTP account I need to use "host|username" syntax, but that does not work in my case when I try to connect using FtpConnection methods in a software I developed.

Is there a way to just pass the user without the hostname?

Your issue has to do with how IIS handles incomming requests. You might want to take a look at: MSDN blog-post

simplest solution would be to run ftp on the 'default website' in IIS
