Fixed: Can't map a network drive in Vista Home & Samba

We had a Vista Home client machine that needed access to a Samba 2.X server. The problem though is that Vista ships with NTLMv2 authentication ONLY as default when we want just NTLM AND NTLMv2 authentication.

There is no Local Security Policy editor in Vista Home, nor can you access it by typing secpol.msc, so we're going to need to edit this via the registry:

1. Open up regedit 

2. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\LMCompatibilityLevel

3. Change the Value from 3 to 1

4. Reboot

5. Map your drive
