I'm using zfd7 agent on win98 machines with nw-client 3.40 Update B .
After installing zfd7 agent everything worked fine. But after some time the
users see the zfd7-agent console to log in instead of the nw-client console
if they start the win98 machine. This happens with some win98-workstations
but not with all.

We don't use xtier server elements.

What must I do to fix this problem ?
The win98 workstations should start with nw-client login-console and there
should be no authentification to xtier by the zfd-agent console.
