I've got 25 comps runnning in a small public library, most for public use in a poor community. Extremely limited funding means we've got a wide variety of machines, many quite old, running a variety of OS's - Windows 98, W2K Pro, and recently, WXP -- some w/SP2, some not. We've also got a librarian (me) with no actual comp training trying to manage them, so please excuse my lack of expertise. We have 2 different IP ranges, because we have 2 sources for our Internet access - both necessary for different purposes. There's no server, just a peer to peer network. All go through one router out to one fractional T1 line.
Up until we added the XP machines, all of the computers could see each other, regardless of their IP address. Well, they could after I added the NetBeui protocol to them, at least. They could all also see the network printer. But a recent grant is allowing us to slowly replace many of the W98 comps with XP machines, and now nothing I do seems to enable the older machines to see or reach the XP ones, and vice-versa, unless they're in the same IP range. They reach the Internet fine, all are in the same workgroup, but until I change the IP address to one in the same range as the other XP machines, they don't see each other and can't reach each other. Because of the need for all to share one LaserJet printer, and the need for many of the machines to access an N2H2 proxy content filter available only via one of the IP ranges, I'm now stuck putting almost all of our comps on one of the IP ranges. I have enough addresses for that, but evidently not enough bandwidth from that source. At peak times the machines using that gateway are now down to worse than dial-up speeds on our fractional T1.
The other IP gateway is to a much faster connection, but if I use it those comps can't reach the filter or print -- not an acceptable answer. Does anybody know a way to get XP (with or without SP2) to play nice with older OS's in a different IP range? I'm sorry to sound so dumb -- I know I'm out of my league here, but this reading this site's past solutions is what usually gets me back on track, so I've got to try. Thanks!
