Description:
Cannot open backup device 'D:\Program Files\Parallels\Plesk\MySQL\Backup\psa-20100721.dump'. Operating system error 5(Access is denied.). BACKUP DATABASE is terminating abnormally.
at (VADOConnection::execute line 90)
at Unable to backup of vital Plesk settings(SettingsBackup::execute line 207)
Execute file name: D:\Program Files\Parallels\Plesk\admin\bin\sshost.exe

Due to these problems in some ocasions mailenable also starts to hickup. mailque is filling up and nothing left afther a while then to reboot the server. However, the problem stays ... Any idea's why the Access would be denied ?
