Networked XP can't access Win7 without Password Protected Sharing

[racecannon]

Two computers, fresh installs on each. A Win7 and WinXP. I setup an administrative user on the Win7 machine using the same username and password as the local user on the WinXP machine. I enable the appropriate permissions in the Sharing and Security tabs of the folder I wish to share on my Win7 machine. The Win7 machine's location is set to Work.

I have a mac that can access the share using the same username and password as the local account on the WinXP machine, but the only way I can get the XP machine to access the share is if I turn off "Password Protected Sharing" on the Win7 machine. I would prefer to require password protected sharing for security on my work network, as there are other computers on the network that I don't want to have access to the Win7 machine.

Can anyone tell if I skipped a step somewhere?

I'm just thinking outloud here, but does XP support the default authentication protocols used by Windows 7?

I don't know but Apple's implementation of SMB works fine in this circumstance.

Same user, pass, and workgroup. Looks like you got that, and the same workgroup isn't always necessary.

On XP, disable the poorly-named simple file sharing option.

On 7:
Public folder sharing: turn off (usually doesn't matter, but for troubleshooting...).
File sharing connections: enable 40/56-bit (yes, an updated XP shouldn't need this set, but it often does).
Password-protected sharing: turn on.
HomeGroup connections: user accounts and passwords.

Samba, as a client, is much more forgiving than Windows itself.
