I'm currently working on a network at a small non-profit organization. There are like 6 computers all networked using a Linksys WRT54G. All the other systems have XP home/pro. This is a brand new Dell Dimension E521 out of the box and it will not display all the other workgroup computers. I have the same workgroup, password sharing off, file sharing on, and have tried disabling the firewall (McAfee). All the other systems can see eachother (except for this one), but this one only displays itself, the shared printer, and the router. The vista box has an internet connection. Any ideas?
