local administrator account locked out.

Hi all,

I have a XP machine that is a member of Win2008 domain and the local
administrator account is locked out

Is it possible for the local administrator account to be locked out ? I
rebooted the PC and still the account is locked out. Also seem strange the
Domain admins group is not a member of the local administrator group..

BTW .. Never thought the local administrator account can be locked out
indefinitely .. If I am correct I believe it should be automatically
unlocked after a reboot , correct ? .. Also is there an account lockout
policy GPO for the local administrator . Is this domain or local GPO?
