policy.client.i.exe error

Hi,

i deploy client LANDesk 8.8. All workstation  running on MS Windows 2000 Pro CZ or MS Windows XP Pro CZ (Vista is OK) on user logon display this error message:

policy.client.i.exe error (OK).

In windows system registry: Service Landesk Policy Invoker was unexpectedly termination (ID 7031).

Any idea? Thanks.
