I am using a Windows Vista laptop. There is another desktop which is on the network and connected to my system through Wifi. It has Windows XP Home SP4 installed in the same. I had connected a Cannon Printer to the desktop. The system works fine and the lan is also working well, but there is some kind of connectivity failure. When I try add printer on my network then I am getting this error -- The Active Directory Domain Service is currently unavailable. My printer looks to be installed and I had also installed its driver in the system. I think this must work.
