Windows 7 Folder Access

Thanks for the replies everyone.

Using the link supplied, I now have an Excel file from Microsoft. I have filtered by Windows 7 support options. Under the security TAB, he available options are:

Microsoft network server: Server SPN target name validation level
Network security: Restrict NTLM: Outgoing NTLM traffic to remote servers
Network security: Restrict NTLM: Incoming NTLM traffic
Network security: Restrict NTLM: Audit Incoming NTLM Traffic
Network security: Restrict NTLM: NTLM authentication in this domain
Network security: Restrict NTLM: Audit NTLM authentication in this domain
Network security: Restrict NTLM: Add remote server exceptions for NTLM authentication
Network security: Restrict NTLM: Add server exceptions in this domain
Network security: Allow LocalSystem NULL session fallback
Network security: Allow Local System to use computer identity for NTLM
Network security: Allow PKU2U authentication requests to this computer to use online identities.
Network security: Configure encryption types allowed for Kerberos

None of which exactly correspond to the advice of changing the settings of "Network Security: LAN Manager authentication level"

Is there anyone who is way better than me at explaining what registry entry I need to go to and what settings I need to alter to achieve the above?

For what it's worth, there are many queries about this problem on the net and it does seem to be a Windows 7 Home Premium (my version) issue. I really hope there is a way to restrict shares to certain users on my network as opposed to giving all users all the Shares :?

Thanks,
Munitions.
