Getting files from a PC via a wireless router?

Question

I am trying to get files from my room mate's laptop by going to Finder and then Network. I see the computer's name (Toshiba-User) with a light gray network icon and when I double click to connect, it shows me the little white bar with the blue lines through it then it says:
"SMB/CIFS File System Authentication
Enter the workgroup or domain and your user name and password to access the server "TOSHIBA-USER."
Workgroup or Domain:
WORKGROUP (<-----that's a text box, I can type whatever I want in it but it's filled out like that automatically.)
Name:
LUIS (<------------That's another blank text box but it's automatically filled out like so)
Password:
(blank text space)
(box) remember this password in my keychain
Cancel OK
My room mate claims to never have set up any kind of "WORKGROUP" and doesn't even know what the password is. I need the assistance of the more mac-experienced!

Answer 1

Actually, you need someone more PC-experienced.
The fact is, if the PC user never defined a workgroup, then 'WORKGROUP' is the default, so that's what his machine is.
Despite how it may look, the Mac doesn't know that, it's just an assumption since it's the default on your Mac, too, unless you've changed it in Directory Access.
As for the Username, it's defaulting to 'Luis' since that's your username on your machine. The Mac OS assumes that your username is the same on the other machine, but if it isn't you're welcome to change it here.
As for the password, the account should have a password set on it - note that this is the password for the account on the remote PC and is in no way related to any password set on your machine.
You'd need to talk to your roommate to find out what username and password you should use to log onto his machine.
If he's truly never set a password on his machine, then the machine should be blank, but that's a horribly scary situation to be in - a Windows system with no password set? :: shudder :: I'm surprised it's not crawling across the desk with all the bugs, spyware and viruses it must be infected with.
