a strange password box

On start up after everything has loaded on my desktop,I get a rectangle box with a password in the middle to be entered.When i try to put something in,Nothing happens!,And the only way to get rid of it is to go to the toolbar,right click it,and left click the 'close' sign twice!. i cant even close it the normal way by clicking the red cross in the box,it doesnt affect me logging on to the network.any help would be grateful. Regards
