Connected..... but cannot log in....

Hi there.

Would love it if someone can help me.

Phone: Galaxy S
OS: Windows 7

I installed the client and server. The phone and the computer connected.

However, the next step is where I got stuck:

On my phone, it shows the Windows Logon Screen (similar to the one where you lock the windows screen). When I click into it, it shows the message: Logon failure user account restriction. Possible reasons are blank passwords not allowed, logon hour restrictions, or a policy restriction has been enforced.

Note that I don't have a password on my computer. I am thinking it's a setting I might need to change on my Windows but I am not sure where.

Please help.
