How to connect using Remote Desktop without a password ?

Sometimes, the default Windows user is setup with a blank password. In such cases Remote Desktop refuses to connect, and it may be inconvenient to require password login for local users.

To change the default Windows behavior and allow login over the local network with blank password, do the following:

1. Start the Windows Registry editor (type regedit in the "Start > Run" dialog)

2. Navigate to:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
"LimitBlankPasswordUse"=dword:00000001


3. Change LimitBlankPasswordUse to 0 (zero) to enable the use of blank passwords, 1 to prevent blank passwords over the network.

Alternatively, you can use group policy to change this behavior, see MSKB 303846
