The NX3100 units show up in OMSE as non-compliant due to an update in th NAS drivers, 1.1.0.0500 shipped with the units but at somepoint they did a slight version change to 1.1.0.0501. OMSE detects this and wants to upgrade it however it can't. If you try to manually update it locally tit tells you update passed (doesn't install) due to the fact that it doesn't think it needs to. The update is only meant to be installed on systems that had a clean install done.
