Microsoft Dynamics Navision 2009 R2

Hi all,
We have Microsoft Dynamics Navision 2009 R2 and I'm trying to figure out why I'm not able to
Import pictures in a 3'rd party addon for Navision called Trimit.

I've tried using processmon which doesn't give me anything usefull.
Examining the application eventlog it throws the message below

This is working when the user connection has local administrative rights on the server

Error message:
