Anonymouse Sharing XP Home, Vista Home, 7 Home Premium

Hi,

I'm having an issue sharing files between my three machines (there are

actually none windows machines as well using SMB share).

They all work with each other except "Windows 7" is misbehaving.

Everyone is prompted for a password to browse the 7 machine, and 7 is

asked for password when it tries to look at any other device.

This is obviously a "password encryption" thing that I have run into

before, but now I cannot seem to find a solution.

I have the following changes to Windows 7:

HKLM\SYSTEM\CurrentControlSet\Control\Lsa

LmCompatibilityLevel=1

Which I think is all I had to do with Vista and XP to get them to cooperate.

Any suggestions?

Thank you.
