Hello,

I want to change the domain administrator's password in a Windows 2008 R2 domain. I need to make sure that I have all services that require administrator's authentication so as not to prevent them from running.
Would be grateful if anyone can assist or hint on some useful documentation.

Thanks a lot.

If you are wanting to find out what services the "built-in administrator" account is using this will be a manual process, as the password is entered manually on the server when settign this up.

It is not a good practice using the administrator account to control services . I would recommend using a services account for this and using a prefix of something like "svc_name" and also setting your services accounts to "password never expires". This way you do not encounter issues like you are experiencing. That being said you will need to manually check all of your servers (services and scheduled tasks) to see if you have used the admin account to control these.

 Once you have done all of the leg work, changing the domain admin password is strightforward as it can be done in ADUC.

Will.

Hi

Have a look at this thread http://www.techsupportforum.com/forums/f103/change-domain-admin-password-514212.html.

Also, i would suggest to create another domain admin user before resetting the root admin password. It will help in case something goes wrong.

You can find such information via PowerShell. Examples below. Although, I would generally advise against using the Domain\Administrator account as a service credential.

get-wmiobject win32_service -comp <domain controller/server name> | Group Startname -NoElement | Sort Count

get-wmiobject win32_service -comp <domain controller/server name> -filter "Startname Like '%Administrator%'" | select name,startname

Etc., just play around with Get-WmiObject...

yep, you are in deeep trouble :))
you did not write down which services are configured manually with that password and on which computer/server.  i still think you have several options:

before doing anything i would recommand that you try the link below to determine if any scripts are configured manually:

http://www.activexperts.com/network-monitor/windowsmanagement/adminscripts/services/#ChangeServiceAccountPassword.htm

Another scenario would be to create a NEW domain admin and disable the current and see if you have any issues.  Because if you change your password anyways and you have some service running with that password configured manually, you will get continous account locked outs on the administrator account.

in that case the script below will help you to determine the location of the service that is running with that password:

Please assign point if OK for you.

Happy troubleshooting!
