If a system administrator user account is disabled due to too many failed login attempts, you may find yourself in a situation where you cannot authenticate to the WS_FTP Server Manager. In this case, you can use iftpaddu.exe command line utility to enable the user account.
To enable a disabled system administrator account using the command line utility:
cmd.exe
and click OK. The command line window opens.iftpaddu.exe -mod -h <host name> -u <user name> +active
, where <user name>
is the name of the user you want to restore and <host name>
is the name of the host to which the user belongs.
