GoDaddy FTP user password reset clears the 530 User cannot log in error.

When trying to connect to the Windows IIS 6.0 based hosting provider for one of our clients that has ASP styled web site with GoDaddy we got an unusual error message within Filezilla,

 Status:    Connecting to x.x.x.x:21...
 Status:    Connection established, waiting for welcome message...
 Response:    220 Microsoft FTP Service
 Command:    USER godaddyftpuser
 Response:    331 Password required for godaddyftpuser.
 Command:    PASS ************
 Response:    530 User godaddyftpuser cannot log in.
 Error:    Critical error
 Error:    Could not connect to server

The web site was working as expected – just no FTP access. To fix this we went into the GoDaddy user account administration window and under the Hosting Control center hosting dashboard we reset the password to the same password that we were using.

The Filezilla client was able to connect. Very odd. Will have to keep an eye on this one.
