We had some similar problems with LCD-Screens.
It could detect them on AIDA but we couldnt send it to NAVISION.
And a guy from AIDA found out that they wasn't in the data-base.
We could see the screens on AIDA like this.
The guy put the screens in the data-base, and then we could transfer from AIDA to NAVISION the screens.
Are you sure this network adapter is in the data-base?
