File Sharing Problems

Ok guys, I'm new to the site, and I'm new to macs. So please have mercy.

(For the record I have searched for days, and can't get help on this issue)

I'm am try to share files from my windows XP desktop computer, to my macbook pro os 10.4, through a linksys wireless network. My notebook is currently connected to the network, meaning I can access the Internet. I try to activate the file sharing on my mac, and it asks me for a password. I have no idea what the password is. What is this "password?" Its not the common password that is set for security reasons on the mac.

I don't understand why it's asking me for a password when I'm already on the network!?? Its not this hard to share between pc's.

Sorry, I'm pretty sure it's 10.5

somebody please?

what does it ask for, your keychain password or user password?

or is it the username and password on your desktop PC?

It says "Enter Your username and password to access file server________"

My name is in the username section and the password section is blank.
My computer password doesn't work, and i've tried leaving it blank.

use the desktop pc username and password for your network, check on the desktop network settings

There is no password for the pc, when the logon screen comes on you just press enter and the comp starts up.

The PC login def does not work.

its not that login, its the one you use for your sharing network settings

Is the name the username on your Mac?

I fixed it. The network sharing on the PC was not enabled. Thanks for your help.
