I tried to set KFW and AFS paths on first position in PATH but it didn't =


And I tried logging before but the eventviewer said only:
[AFS Client] OpenAFS Start Pending.
[AFS Client] Security Level is Clear.
[AFS Client] OpenAFS Running.
[AFS Logon] Integrated login failed: Authentication Server was unavailabl=

I tried now KFW 3.2.3 alpha but it made no difference.

Would it be an option to copy all KFW files to \Windows directory?
