43 2014-01-13 13:41 Fix Samba and Windows Vista/7/8

Not sure why I didn't save this when I set up Win 7 a couple years ago. Setting up Win 8 now it wouldn't connect to shares on my NAS, and I had to search again for the setting to fix it. And the answer was a needle in a haystack of search results:

From: http://arouter.blogspot.com/2011/07/samba-file-server-on-dd-wrt.html:

When accessing Samba from a Windows Vista/7 machine, the password will
always be rejected regardless whatever you input. That's because the
Samba we used here does not support the new password authorization
scheme in Windows.

To fix:
Run secpol.msc Go to: Local Policies -> Security Options
Find "Network Security: LAN Manager authentication level" and change
setting from "Send NTLMv2 response only" to "Send LM & NTLM - use
NTLMv2 session security if negotiated"

Some Windows versions may not have secpol.msc, in this case, save
these 3 lines below to file sambafix.reg and run it:

Windows Registry Editor Version 5.00
Reboot the Windows to make the change take effect.
