Computer disappearing from home network

This says that dual homed computers may have problems with the MS Computer Browser service. (i.e. those machines with two IP addresses from two (real or virtual) network adaptors). This applies to machines with Hamachi, which is like OpenVPN, and installs a second, virtual, network adaptor. I found that if you disable NetBios over TCP/IP on the additional adaptor the Computer Browser service does not 'see' the additional adaptor and works fine.
