Upgrading OS X to Leopard
Summary
I tried to sort it out by changing symlinks in the system folders, uninstalling the beta, but basically just broke everything. I decided to reinstall the whole thing, which requires you to notice the customise button on the installer, allowing you to request it clear the disk first (but usefully also allows you to not install various things like printer device drivers which saves you gigs of space ! I installed it, it detected my bootcamp partition, but trying to run it caused an immediate OS X crash. A copy of the files from another XP SP2 installation fixed the issue (via Safemode and a USB key) , returning change dates back to 2004, got everything working perfectly again. Looking on the net, there were suggestions that the resolver stack had changed slightly in the new OS, and may be working badly with old routers / dns servers in some way.
