Settings (in Vista and Windows 7) to access Samba Shares...

Microsoft Vista’s default security policy is to only use NTLMv2 authentication. I am not sure what the setting is by default in Windows 7 - so this may apply there too.

Windows 7 Upgrade Clean Install - How to get it to accept the Upgrade Key

How to Install Windows 7 to a NEW Drive using an Upgrade DVD

I recently had to deal with Microsoft Support on this issue, and I can save you a great deal of time by passing on this procedure to you.

Go to:

And make a pledge if you too would like them to continue to offer their service...
