MySQL Fatal error: Can't open privilege tables: Table 'mysql.host' doesn't exist

[cylando]

Hoffe, dass mir jemand weiterhelfen kann.

Ich habe auf einem W2K-Server MySQL installiert. Soweit lief auch alles gut, bis ich den Server neu starten musste.
Nun lässt sich MySQL weder als Dienst noch als Standalone starten.

Die Error-Datei gibt folgende Fehler aus:

Wie ersichtlich kann MySQL anscheinend nicht starten, da die InnoDB einen Fehler verursacht (Fatal error: Can't open privilege tables: Table 'mysql.host' doesn't exist)

Da ich in MySQL nicht so bewandert bin (blutiger newbie) sagt mir die Fehlermeldung nichts. Ich wüsste auch nicht, dass ich die InnoDB verwende. Auf dem Server sehe ich auch keine InnoDB Dateien oder Verzeichnisse.

Falls notwendig, kann ich auch die my.cfg posten.

Wäre für eine rasche Hilfe sehr dankbar!
