I have a 10-license network key.
Running XP sp2 with the firewalls properly configured on server-side and end user-side.
The WIBU Key service keeps stopping and crashing WkSvW32.exe (not sure in which order, but definitely related), and thus the end users lose connectivity. The physical USB network key isn't likely to be malfunctioning, because this Graphisoft sent me a new key this week. The USB ports are good. I've tried running the server monitoring on various machines with the same result.
It seems to crash once a second user logs on, however, earlier today, I got 4 or 5 licenses used without trouble.
Is there some recent Windows update that conflicts with the WIBU software?
