Windows cannot load extension scecli.dll

I have a Windows XP SP2 workstation (part of the Windows 2003 domain) that
reports Event ID 1036 from userenv every time it processes the group policy.
(Windows cannot load extension scecli.dll. (The specified module could not
be found. ).For more information, see Help and Support Center at
http://go.microsoft.com/fwlink/events.asp.)

If i run the rsop.msc on the workstation, i get an exclamation mark under
computer configuration and when i look at the error information i see an
erorr under Security component. Running secedit on the workstation also
generates an error (didn't write down the text of the error)

Can this be repaird?

Thanks
