unable to install due to lack of admin rights

[arrowdownhill]

Hello everyone,
So I'm configuring a laptop for a new employee that will be starting in a few days. This is a routine process but for some reason things are different this time. I have added the administrator account to the domain i need to access, but after logging in it fails to show me any of the files that are stored on the server we use.
So when I manage the user accounts and check to see if I am using an account it tells me that i have full admin rights.

So I logged back off and logged in using our work admin account. (This account is used to install the software from our server onto the pc/laptop.) This is where I need to be to access all of the files needed to get this machine running.

Usually, its no problem. I log on and install the software and I'm done. This time however, I am being stopped by an error that says I do not have the admin rights to install or change anything. I am clearly using an account with admin rights but I cannot install anything, nor can I add anything to the members group of any account. It only says access is denied.

Is there a way that I can get around this? I am completely confused as to why this machine would prevent me from installing anything or making changes to anything when I have done nothing different when building this machine.

I'm trying to be as helpful to you as I can, but explaining the situation has proven to be MORE of a challenge! So, if you can translate this cry for help into anything that could help me to find a solution it would be greatly appreciated. I am just out of ideas.

Thanks everyone.
