How to allow Windows Vista to logon to a Buffalo NAS box / Linkstation / Terrastation

If you can't log into your Buffalo NAS box it's because of Microsoft updating the system for the greater good of encouraging me to switch to Apple sooner.

The symptoms:

The NAS box drive appears in the Network folder

You can access the NAS box via Window XP

You can't logon and it might seem to you that the login details are wrong

You can get the to web control panel using its IP e.g http://192.168.0.20

The cause:

Vista uses the NTLMv2 protocol, which Samba on the box does not support.

The solution:

Go to Start > Run > "secpol.msc"

Local Policies ; Security Options ; Network Security; LAN Manager authentication level.

Change from "Send NTLMv2 response only" to "Send LM & NTLM - use NTLMv2 session security if negotiated". Click OK.
