One possible cause is that the PATH environment variable on the machine
was longer than the max length prior to the installation of KFW and
therefore the Kerberos libraries cannot be found by afslogon.dll.

Regardless of the actual cause the place to start is by enabling
debug logging to the Windows Application Event Log of the integrated
logon actions.  Please see section 4.6 of
