Helping a friend connect to an SMB share from a Windows 8 machine, every time we connected it would prompt the username and password which we entered, then it would come back as failed, incorrect details. We think it was either v1 or v2, and the default security policy in Windows 8 is set not to allow these connections by default. We finally managed to get it working using the following settings found on this post (http://superuser.com/questions/115337/windows-7-connecting-to-samba-shares):
1) Run: gpedit.msc
2) Find:
Console Root -> Local Computer Policy -> Computer Configuration -> Windows Settings -> -> Security Settings -> Local Policies ->Security Options
When you're there change the following policies
3) Microsoft network client: Send unencrypted password to third-party SMB server: Switch it to "Enabled".
4) Network security: LAN Manager authentication level: Select the option: Send LM & NTLM - use NTLMv2 session security if negotiated.
5) Reboot
6) Successfully connect!
