<p>Reason is that in a domain, the direct child-objects of the domain-object are not only computers, but also other objects, which do not have an ip address. The ip address resolution therefore fails.</p>

<p>Solution is that we need to check <a href="https://github.com/MediaPortal/MediaPortal-2/blob/1fcf783e56c55e96ae9c0e490a4b5b5b7be5487f/MediaPortal/Source/Extensions/ResourceProviders/NetworkNeighborhoodResourceProvider/NeighborhoodBrowser/DirectoryEntryNeighborhoodBrowser.cs#L90">here</a>, whether the object is a computer, before we try to relove the ip address.</p>
