Re: Windows 7 and QNTC

[Vernon Hamberg <vhamberg@xxxxxxxxxxxxxxx>]

This was discussed here recently - I had trouble with setting up mapped 
drives from Win 7 64-bit and fixed it with the change Steve mentions.

To explain further, take these steps to change a local security policy -
1. In Run, type "secpol.msc" and press enter - or type this in the 
search box when you click on Start
2. Click on the plus sign by "Local Policies" to open it further
3. Click on "Security Policies" to get a list in the right-hand panel
4. Find the “Network security: LAN Manager authentication level” item 
and double-click it
5. Set it to “Send LM & NTLM – use NTLMv2 session security if negotiated”

Here is a link that gives an alternative if you have Win 7 Home -
