Administrator Account is Locked in Domain Area

Hi There,

I've a problem with ALL my Windows 7 Laptop ini my office. We have 5 Laptop with Windows 7 installed in it. A week ago, everything is doing Normally. I make those 5 laptops join domain, and I make the user in domain as an administrator in their local Laptop. But in last Monday, everything going strange:

1. When I logging in using their account, I can enter the desktop. But when I try to access some programs that need Administrator Account, it become errors and said that I must administrator privilege to access this programs.

2. I try to access user account in control panel, and when I see the user list, it become BLANK. No user defined even an administrator too. When I try to add new user in it, it said that I didn't have Administrator privilege (again).

3. I try to logging in using Local Administrator, but in the log in menu, it said that the administrator account is disabled. How Come?

4. The only way I can access with administrator privilege is using the Domain Administrator. I try to configure again, and when I restart, everything has gone again.

can some 1 give me advise regarding this matter? should I reinstall it again?
thanks Guys.

Welcome to SF,

Seems to be there have been some local security policies and/ or domain using GPO setup in your network by the Network Admin. Are you part of your IT Dept?

Yups. That's correct. I'm using Active Directory with Windows Server 2008. Can you advise regarding this matter?

You will have to contact someone Whoever setup those policies in your network and have that person help you out. If you setup these policies I assume that you would be able to undo.

What kind of policy? can you advise it? I just confused that, this only happened in Windows 7 only. I can access user with administrator privilege as an admin in XP. The main strange is, this happened during this week. because last 2 months, everythings are alright.
