• FileZilla:
• [/b]

Error: Critical error: Could not connect to server
Cause
When Windows Server is connected to a domain (Active Directory), an FTP user is treated as a domain user.

Resolution
Use the "hostname\FTP login" pair as a username for FTP connections:

1.Find a server hostname:

C:\> hostname
WIN-PLESK-SERVER
2.Use this hostname together with an FTP login as a username. For example:

C:\> ftp 203.0.113.2
Connected to 203.0.113.2.
220 Microsoft FTP Service
User (203.0.113.2:(none)): WIN-PLESK-SERVER\john_doe
331 Password required
Password:
230 User logged in.
ftp> ls
200 PORT command successful.
Alternatively, use the "Active Directory domain name_\FTP login_" pair:

C:\> ftp **203.0.113.2
**Connected to 203.0.113.2.
220 Microsoft FTP Service
User (203.0.113.2:(none)): pleskserver\john_doe
