Alsoooo, ich habe die großen Weiten des WWWs erforscht und habe etwas gefunden was bei der Lösung des beschriebenen Problems helfen könnte ...
Event-ID Recherche:
Value 1326 - "Logon failure: unknown user name or bad password." - I had this error filling up my event viewers on two servers for days. I had scheduled backups under my user name and password. After I changed my password I started getting the errors. I fixed it by rescheduling the jobs under my user name and new password; problem resolved.
This error may occur when an user account is left logged onto a PC, and is disabled by an administrator in the background. Once the Disabled ID is logged off, the error goes away.
I had this problem on a Windows 2000 DC. It turned out it was caused by ZoneAlarm firewall.

Value 1326 - "Logon failure: unknown user name or bad password." - This will occur if a Terminal Session is disconnected and not logged off and susequently the users logon password is changed. You will still have access to the "stale" session with the new password. This commonly happens with Administrators, who leave the session open by disconnecting so as to leave a program running. Since an Administrator can log back onto the session with the new password it can be overlooked. Terminate the Terminal Services session by logging out and the problem will disappear.

Natüüüürlich, ich hätte auch eher drauf kommen können da zu suchen, aber die ersten "Such-Versuche" waren anscheinend etwas ungenau, da hatte ich etwas arg viele Suchergebnisse und sich da durchzuwühlen kann schon ziemlich lange dauern ...
Also denn ...
Hasta la vista muchachos ...
