It works for me, did you check the impersonating identity in your timer
event handler?
Note also that your code is impersonating an interactive logon type, why?
This is not needed, you should use batch or network type logons, interactive
is way too expensive and you need to create an impersonating token from the
direct token which is another expensive action.
