Das ist was mir der Lotus Support zu dem Problem geschrieben hat. Die Fehlermeldung zeigt keine Auswirkung, deshalb habe ich es nicht mehr weiter verfolgt.

Problem: Enabling Ichitaro format in full-text search
In a Japanese system environment, either while the Sametime Server is installed or after you start the Domino server, you may see the following error.
"Unable to load FT alternate filter config file: C:\Domino\ FTAF.ncf."
Solution: Ignore the error when you install the Sametime Server. To enable the Ichitaro attachment document full-text search after you install it, set the following NOTES.INI variable: ft_use_altfltr=1.
The ftaf.ncf file is automatically installed in your Notes program directory. You should also set two values in the ftaf.ncf file:
aftaro6
aftaro9
Copy the ftaf.ncf file into your Domino program directory.
An example of the ftaf.ncf file follows:
************BEGINNING OF DATA**************
aftaro6
aftaro9
************END OF DATA********************
23931
***********************
How I can undestand, you need to worry about FTAF.ncf only if you are working with Japanese environment and need to work with Ichitaro format.
If you do not need this format, please remove line ft_use_altfltr= out of you notes.ini(I checked it, you have it).
If you need it, please correct this line in notes.ini and verify that you created FTAF.ncf(see below).
Hoffe das hilft.
