I know this has been asked on numerous sites, with some differences, but I cannot find an answer, no matter how many ways I google it.... and Apple's discussion boards have not yet helped. From 10.5.0 to possibly 10.5.2, shared volumes would sporadically show up in the sidebar. However, now (and not sure if this started with 10.5.2 or 10.5.3), ONLY Mac shared volumes will show up. Leopard will not show me any Windows shared volumes. This is quite frustrating because my Powerbook with 10.3.9 sees the Dell in our place and so does my G5 running 10.4.11. Just go to the Network folder and there it is, along with all the Macs. Leopard will only mount the Dell volume through "connect to server," followed by entering in the Dell's IP address. I have tried rebooting the computers, the router, enabled NetBIOS for whatever reason on the Dell, but nothing makes 10.5.3 see this Dell without manually connecting to an IP. Lastly, I know the MBP is at fault because I tested it at a friend's house. He, too, has the same MBP as I do, with 10.5.3 also. He sees everything; I only see the Macs. I really don't want to go through the hassle of archive and install. Does anyone have anything I might try? I've thrown out preferences galore and still nothing. Thanks.
