I have just bought a Macbook Pro running OS 10.7.3 Lion. I want to connect it to an existing PC workgroup via my Belkin wireless router. I have successfully accessed the internet on the Macbook via the router, but I am unable to connect it successfully to the workgroup. I have done everything mentioned on previous threads - the latest for a Mac runnimg Leopard - but still won't connect. I can see the icon for the Macbook on my PC workgroup page, but when I double click the icon I get the error message: \\Macbookpro-2098 is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permission The network path was not found. I have an old Windows Laptop connected by ethernet cable directly to the router and that is able to see the Macbook documents. However I can't see either the PC or Laptop on the Macbook. The PC and laptop are running Windows XP. I'm not sure where to go from here!!
