Problem:


Having an issue while connecting to the IIS FTP service on my server by using Cute FTP. Got disconnection after the command FEAT

Resolution


The FTP command "FEAT" may be a root cause for this issue. You can close the FEAT in the CuteFTP or disable FEAT.
  1. Menu Tools > Global Options
  2. Click Connections in the left pane.
  3. Turn off "Sent FEAT command after login to determine feature support"
  4. Click OK.
