Windows 2008 Local Admin and Domain Admin Password change in windows server 2008 R2

The problem with the AutoAdminLogon solutions given by others is that the password still has to be supplied in the registry, and the password will still expire, even with it enabled.

So while doing what I am about to suggest is usually a Bad Idea™ under normal circumstances, in this particular case, being a demo domain controller, you will need to do both of the following to achieve what you are asking:

1. Change the domain's password policy using Group Policy Management (gpmc.msc)

   • Enforce password history: 0 passwords remembered
   • Maximum password age: 0 days
   • Minimum password age: 0 days
   • Minimum password length: 0 characters
   • Passwords must meet complexity requirements: Disabled

2. Change the Administrator user's account in Active Directory Users and Computers (dsa.msc)

   • Password never expires: check

After changing the settings noted above, you should be able to change the password of the Administrator to a blank password, and it should not expire (unless there is some other policy (perhaps at a Forest level) that overrides the change (if so, you can use the Resultant Set of Policy console (rsop.msc) to find where the policy is being set.

For each XP workstation, use a startup batch file script in %userprofile%\Start Menu\Programs\Startup like so:

net use <drive letter>: \\<servername or ip>\<sharename> /USER:<username> <password> /Y
