By 1992, however, new life had been breathed into peer-to-peer networking by both Novell and Microsoft, along with the popularity of Artisoft's LANtastic. Even though the earliest LANs were of this genre, by 1989 it appeared that they were on the way out. We will take a close look at peer-to-peer LANs at a deeper level in some future posts
