We have any workstations where the remote client install doesn't work

ZAM manager reports that the client install was successful but there are
only 3 files ( _TSCUninst.exe, cclient.exe, CClientSvc.exe ) ) in the
Program Files\Novell\ZENworks\Asset Management\bin directory of
workstation. Meanwhile CClientSvc service is running nothing happens. No
more files download from server.

CClientEvent logfile has an event in every 10 minutes like this:
<EVENT AT="3/01/2007 10:37:13">
CPS.INI problem

What does it mean? Any suggestions?
