Unable to log in with same user account on windows 7.

I am using multiple independent workstation on the same computer. Basically i am able to turn 1 computer into the 2 .

My monitor 1 is 1 user , my monitor 2 is another user.

I want to be able to log in with the same admin account on windows 7, but when i try to log in on the second workstation i get this message : logon failure user not allowed to log onto this computer windows 7

When i use a standard user on the monitor 2 , there is no issue. But if i try to use my admin account to login i get that message.

Is there a way for a standard user account to have full access to a Admin account Desktop?

The apllication i am using is Softxpand:
SoftXpand 2011 is a multi-seat software that turns any standard Windows PC into multiple independent workstations. Each workstation operates totally independently and offers top performance and high flexibility. That means each user may run several heavy applications simultaneously, including, for example, a heavy graphic application, multi-media software, integrated learning systems and curriculum-oriented programs.

It's very difficult to say what's going on without more information as to how it works under the hood, and their website is extremely vague.

Is there a way for a standard user account to have full access to a Admin account Desktop?

I would sincerely hope not. If possible it would be a serious security risk.
