Cant Access WIndows XP Machine form 7. Asks for a password [LAN]

hello,

I am using Windows 7 64bit. I have another XP machine in my LAN. Windows 7 can see the Xp machine in the network tab. But when I try to access it, it prompts for a user name and password.

I've tried setting up a password in my XP machine. Still when i try to connect to the xp machine from 7, i get window prompting for password.

I've been seen different threads but still no luck.

Thanks in advanced :)

Here is the screenshot. [Ps. its a windows 8 theme]

I have turned of "password protected file sharing" in control panel

Thanks very much for the reply

I have no password for my user account in windows 7. So I put my usename "saffat" and kept the password blank. Then this happens

SO my laptops user name is "Plabon". i've entered it and it has no password so i've kept it blank. Still no connection

Well, I've entered "PLABON-LAPTOP/PLABON" and then this comes up
