File shares are enabled on all computers, and the other 14 computers on the network see each other perfectly. The computers are all in the same workgroup as well. An interesting piece of this is that the offending computer, which is XP Pro, can see 5 of the other computers in the network when I got to "view other computers within workgroup), whereas all of the other computers can't be seen. All of the other computers can be accessed by directly typing in the IP in the "my network places" address bar, such as \\192.168.15.100 . All computers can be pinged from the offending computer as well. There is no central server, since this is a workgroup, so I believe that is technically a peer to peer network. I have forced a computer to be a "server" in that it is always the master browser (through small registry changes) and it has a static IP. I have also enabled NetBIOS over TCP/IP for all computers. Since I can ping and directly view computers with knowledge of their IP, it just seems like I'm not recieving updates from the master browser, or the computer is not accepting them. Thank you for trying to help me with this. I have spent a lot of time researching this topic, and this is the last offending computer I just can't figure out. Also of note, I have disable all firewalls and completed uninstalled any trace of norton software on the computer. I also uninstalled and reinstalled all network drivers on the computer as well. Please ask me any more questions that may be of interest.
