you should revert the registry hack after having upgraded your network 
to AD authentication. It is not necessary anymore and may have some

Network neighborhood is not implemented in Samba-AD. It is not very 
efficient and is usually disabled on large network. One should 
definitely learn to do without it (sorry, no choice here).

The desktop is probably doing some broadcasting to find its neighbors, 
which is not very reliable. Anyway, from a security point of view you 
should aim at completely remove NetBIOS from your network. NetBIOS has 
been designed 30 years ago without much security or scalability in mind!
