"Configuration task" is not working

Hi all,
got a problem pushing out a configuration task to a single workstation, the task completes with the following error
Client : Domain / Client Name
Date : 11 minutes ago
State : Error
State Text : Task processing error, error code: (1007,14,0)

Now I suspect the problem is with the workstation, as the reason I was trying to push a new config is that it is not updating definitions from the mirror as the other 19 clients are.

But oddly it is connecting to the RA server at regular intervals and I have just successfully "Updated" the workstation to 4.2.40 from 4.2.35 using RA

anyone any ideas?

RA Server 4.0.122
RA Console 4.0.122
NOD 4.2.40
Client OS Vista Ultimate 6.0.6000

 

There was a problem applying the configuration task on the client. Could you upload the xml file somewhere and provide the link here?
