The following error appears when attempting to log into Plesk:
ERROR: Exception Unable to logon user (Plesk Administrator): (1326) The user name or password is incorrect.
The following error can be seen in the Event Viewer:
Unhanded exception Execute file name: C:\Program Files (x86)\Parallels\Plesk\admin\bin\plesksrv.exe Unable to thread impersonate run without profile: Unable to logon user (\Plesk Administrator): (1326) Logon failure: unknown user name or bad password. Execute file name: C:\Program Files (x86)\Parallels\Plesk\admin\bin\plesksrv.exe
Plesk Administrator users are missing on the server and lacking the necessary permissions.
Check if the
Plesk Administratorusers exist via Administrative tools > Computer Management > Local Users and Groups > Users.
If one is missing, recreate it: Right Click on the Users > New Users > and specify the following parameters:
**psaadm** User name: psaadm Description: Plesk admin account Check 'User cannot change password' and 'Password never expires' **Plesk Administrator** User name: Plesk Administrator Description: Plesk Administrator account Check 'User cannot change password' and 'Password never expires' It should be a member of the Administrators group
Fix permissions with Start > All Programs > Plesk > Plesk Reconfigurator > Check Component and Folder Permissions and Correct disk permissions. Alternatively, you can run the following command in PowerShell:
PS > & "$env:plesk_bin\reconfigurator" /check=Accounts,MySQLDataFileSecurity /no-gui
If Plesk is still not accessible, but with the following error:
Access denied for user 'admin'@'localhost' (using password: YES)
Then refer to the KB #119188 to reset password for the admin MySQL user.
