Can domain-joined computers still join a homegroup?
Yes. Domain-joined computers can join a homegroup and access shared resources; however, they cannot share Libraries or printers on the homegroup. For example, if you take your work computer home and connect to the home network, you can join the computer to the homegroup. You can then access files and printers from your home computers on your work computer. You cannot access files and printers from your work computer on your home computers, though.
