Windows 7: "Unknown username or bad password"

20 Aug 2010   #1

Windows 8 Pro x64; Win 7 Home Premium x64 SP1 on VirtualBox
"Unknown username or bad password"

Hi all,

I get this error message when I try to access any XP computer on my workgorup: "Logon failure: unknown user name or bad password.". I have never experienced this problem before. My laptop is the only computer in the house with Windows 7 on it, and before I have been able to access shared files and folders on the other XP computers in the same workgroup. I am trying to access a shared printer on one of my XP desktops, but I cannot access it due to this error message. I have tried googling, but nothing has worked for me. Does anybody know how to get rid of this error message?

Windows 7 Ult, Windows 8.1 Pro,

Hello McDougal, it might be worth trying to turn off "simple file sharing" on the XP pro machines first. This setting can cause problems with seeing other machines and sharing.

Also go into the Advanced sharing settings and make sure that you have password protected sharing turned off in both the Home-Work and the public file sharing windows. There are two windows under advanced sharing settings.

Next make sure that the time/date is the same on all your machines.

If none of that works then try this registry adjustment.

create or modify 32-bit DWORD: LocalAccountTokenFilterPolicy
set the value to: 1
