I am trying to setup a workgroup between 2 computers in my house that are connected through a router. In the workgroup only one computer (computer 2) shows up. Computer 2 shows up in the workgroup on both computer 1 and computer 2. Computer 1 will not show up in the workgroup on either computer. Both computers are running Win XP SP2 with Norton Internet Security 2006. Does anyone know how I can correct this? Thanks!
