When I open File Manager in the Parallels Plesk Panel (PP) web interface, I get the following error:

    FileList::init() failed: ls_dir_wrapper() failed: Unable to logon user (PLESK900W2K3\USER1): (1326) Logon failure: unknown user name or bad password.

Please note that this part is applicable for Plesk server where passwords are not encrypted, i.e. "Enhanced security mode" is not enabled in Plesk Control panel->Tools and Settings->Security Policy:

    1. Retrieve the password of the domain owner from the Plesk database with the command below (USER1 is the owner of the domain and can be taken from the error message):

        "%plesk_bin%"\dbclient --direct-sql --sql="select su.login, a.password from accounts a, sys_users su  where and su.login='USER1'"
        login       password
        USER1  p@ssw0rd

    2. Check if the user account associated with the domain is enabled:

            - Log into the server with administrative permissions

            - Open *Server Manager > Tools > Computer Management** or run `lusrmgr.msc`

            - Open **Local Users and Groups > Users** and find account `USER1`

            - Right click on account and choose **Properties** 

            - Make sure that checkbox **"Account is disabled"** is disabled.    

    3. Synchronize the system password in accordance with the one retrieved on the first step as follows:

            net user USER1 p@ssw0rd

If "Enhanced security mode" policy is enabled:

    1. Login to Plesk Control panel->subscriptions->domain.tld->change hosting settings and update password for FTP user.
