Yes, this is possible.
By default, Windows will not allow the logon over a network with a blank password. There is a KB article that details how to allow blank passwords for network logons.
You can disable blank password restrictions by using a policy. To locate and change this policy:
- Click Start, point to Run, type gpedit.msc, and then click OK to start the Group Policy Editor.
- Open Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options\Accounts: Limit local account use of blank passwords to console logon only.
- Double-click Limit local account use of blank passwords to consol logon only.
- Click Disabled, and then click OK.
- Quit Group Policy Editor.
NOTE: By default, this policy is on (enabled).
Under the cover, in Registry, this is controlled by
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa]
"LimitBlankPasswordUse"=dword:00000000
Therefore, alternatively, this can be achieved by directly setting LimitBlankPasswordUse
to 0
. Setting it to 1
will restore the default behavior.
After you have enabled this, you will be allowed to log on using a blank password.
