On a Windows PC, you can see the login window where you are connected.
Just below the password box, there is "log onto: and there is says, for example, AD or DJF or ... etc. Otherwise, you can press the Window key and type System and press Enter. Then you enter the system where you under "Domain" can see whether you are connected to Uni-AD or, for example, WORKGROUP, ad.nfit.au.dk, iha.dk, etc.
If you are not connected to Uni-AD, please contact your IT-employee/IT-helpdesk.
