Filesharing in Lion

Hello,

recently I updated my Mac to OS X Lion and since then the filesharing with Windows 7 machines doesn't work anymore:

My brother's PC and we use the same router. By that he was able to access my music, documents and other stuff.

But now the box with my name in System Preferences -> File Sharing is unticked and if i want to tick it my machine asks for a password to enter which is neither my system password nor the network password of my brother's PC.

Anyone has the same problem or a suggestion how to make filesharing between PC and OS X Lion work?

Thanks in advance.

The password you're being prompted for is your OS X admin password (the password you set up for your Mac when you booted it up for the first time). It sounds like you may have forgotten it.

Here's how to reset your password:

Reset a Mac admin password with the OS X Reset Password utility | TechRepublic

But if I change any settings and the Mac asks for the password, my password is accepted...

Have you set SMB sharing up? Might want to go in and check on the per-user basis.

I'm sorry, I had assumed you were unlocking the Sharing preference. It sounds more like you've successfully done that and are now being prompted for credentials to authenticate to your brother's machine.

Here's a fairly comprehensive guide I would encourage you to review:

And let us know how you make out.

@ Dysfunction:

I have set the SMB sharing up.

@cwa107:
Step6 - second picture is the "end" of what is working

and my brother says that at Step9 - second picture he tried to log in with my username and password but it didn't work.
But he entered the netwerk not by typing the IP address into the text field but he just clicked at "network" on the left at the Windows-Explorer (ref.: http://windowsteamblog.com/cfs-file...stAttachments/00.00.50.26.86/userprofile1.jpg) and then double-click on "MACBOOKPRO...":

And just for information the green light is on and it says: "File Sharing: On".

Doesn't has anyone more Ideas?
