Unable to locate device file error on 1.21 Build 986

When using CDJ with SlinkX the client reports the following (abridged output). The files referred to exist and no access restrictions apply.

CDJ is unable to locate the Sony CDP-CX260 across DCOM.

I've checked the DCOM side of things using the E-Z Learn application - and all is well. Any ideas?

Thanks,
Chris.
