I own a macbook pro 10.6.4 and in the office we have an imac and 7 windows 7 pc. Till last week I could able to see all the computers on the network under "Shared" and able to connect them. Office printer is shared via one of the pc thats why I cannot add it to use. I can connect them with "connect server" by using their ip or names. Also I can only see imac under "Shared". How can I be able to see all the computers under "Shared" again and add the printer. Thank you.
