Local log on policy prohibits interactive logon

Hi,
My computers are configured to allow Remote Desktop Connections. I am trying to log on via Remote Desktop Connection to one of my computers. The connection is established and I receive the log in window.
I however cannot log in.
When I fill in the user name and password, I get an error which says that the local policy of this system does not allow interactive you to log on interactively.
I have tried to log on using several different user accounts and I tried logging on from more than one computer on my network, but I keep getting the same error message on all computers. Please solve this.
Thanks!
Error message below:

Logon Message
The local policy of this system does not permit you to logon interactively.
OK
