RE: Locked out local admin accounts...

RSoP = Result Set of Policy
GPMC = Group Policy Management Console (see

Man, if you are managing a Windows domain without the GPMC you are MAD! 

The GPMC is one of the best tools that Microsoft has produced in a long time
and it has been a life saviour in all AD projects that I have participated.

You will need 1 windows XP computer (or Virtual PC) to install it since it
doesn't work on windows 2000 (but don't worry, it will work perfectly with a
windows 2000 domain).

If you don't have windows XP in your environment BUY ONE licence. Just the
use that you will get from the GPMC will make it worth it (buy a laptop that
comes with it installed).

Just to make sure that you are convinced; here is what you can do with the
GPMC that you cannot do (easily or at all) with windows 2000 tools:

 - Map in a nice tree all GPOs that exist and where they are applied
 - Create nice reports with individual GPO settings
 - Create nice reports with the GPOs (both machine and user) that are
applied to a particular computer or server
 - troubleshoot GPOs issues
 - Simulate what would happen if a GPO where applied in a particular OU
 - BACKUP all your GPOs
 - BACKUP individual GPOs
 - RESTORE all GPOs
 - RESTORE individual GPOs
 - easily import/export GPOs from one domain to another (for example from a
'test environment' to a 'live environment')
 - Script all of the above!

Hope this helps

I'm sorry. I don't know all those acronyms. GPO = Group Policy ?

RSoP = ?
GPMC = ?

We don't have any XP computers in our environment, so I'm not sure I'll be
able to use the GPMC. It's also intersting that the local admin accounts
aren't getting locked on all machines, only select ones, albeit in large
numbers.

Thanks for your help,

Ryan

That sounds like a GPO problem since there is one setting which disables
the
local administrator account.

Do some RSoP analysis on the affected computers using the GPMC (you will
need a XP box to run it)

In our environment today, local administrator accounts on workstations
and
servers have been getting locked out at an alarming rate. Nothing crazy
is
standing out on the IDS, and the security logs on the machines that are
having the administrator account locked out aren't showing any login
attempts. What could be going on here? We're a Win2000 environment, and
domain accounts seem to be unaffected, it's only the local administrator
accounts that are getting locked.

This is very bizarre.

Thanks for your help,

Ryan Murphy
