I've got a Powermac G5 and a Powerbook G4 that I use at work. Work is a school, and we've got two campuses. For conversation's sake, I'll refer to them as "Campus 1" and "Campus 2." The G5 is permanently located at Campus 1. When I'm at Campus 1, both of my computers can see each other on the network. I can connect to volumes, share my iTunes libraries, etc., without any special settings. All I have to do is go to one computer and find the other on the network and it connects. The problem enlies when I bring my Powerbook up with me to Campus 2. Campus 1 and Campus 2 are connected together via a T-1 line, and each campus is on it's own subnet. When I turn on my Powerbook and go into "Network," it shows an icon for the G5, but it's grayed out. When I double click on it, it says "the alias 'mguditesg5' could not be opened, because the original item cannot be found." I can't open shares on ANY Campus 1 computer from Campus 2, whether it be a Windows machine or a Mac. I'm even running Thursby Dave 5.0 on the G5 in an effort to make it more Windows compatible, and even that doesn't seem to help. The thing that gets me is that on all of the Windows computers, the fact that I'm on another campus makes no difference--the T-1 line is totally "transparent" to users at each campus. I can be at Campus 2 and open a share on a computer at Campus 1 like I was sitting there at Campus 1. It works just the same, and with no additional configuration at the client end. Now, one thing that I am able to do is connect via IP. What I have to do every time I go to Campus 2 is go to a Windows computer, type in "ping mguditesg5," it gives me the IP address for my G5 at Campus 1, and then on my Powerbook I can do a Apple-K, type in the IP address instead of "mguditesg5," and it connects to it like normal. I have to do this in order to connect to Windows shares as well. This is an okay temporary solution but it's a pain in the ass. This suggests to me some kind of DNS issue...but how do I resolve it?
