disable blank password

So you have computer "A" and computer "B" hooked up on a network. On computer A you configure a folder (or printer) as shared. From computer B you browse the network and attempt to access computer A, then BAM! The dang thing asks for a user name and password.

But wait, you wonder. There is no password set for any user account on computer A. At this point you can go to computer A and configure a password for the account, but if you don't wanna. 

Here's what to do:

For Windows XP Home users: 

- Go to Start menu, click on RUN, type "regedit" and press ENTER on keyboard
- browser to this key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
- double-click on the key named "limitblankpassworduse"
- change the 1 to 0

For Windows XP Professional users: 

- Go to Start menu, Control Panel, Administrative Tools
- Look for Local Security Policy
- then Security Settings\Local Policies
- then Security Options Accounts: Limit local account use of blank passwords to console logon only. 
- This is enabled by default, disable it
