For reasons I am not sure about NDS became screwed up during the install
of a SBS 6.0 server.

Rather than re-install the server from scratch I removed NDS and installed
it again.

Are there any extra steps I need to do to get BM 3.6 working ?

i.e. are there any NDS objects that BM needs in order to work, I will be
using VPN.
