We're trying to figure this question out. Again, simple lab install of a product using the newest available media...problem after undocumented problem have cropped up, and nobody within our reach seems to have any concrete answers (or blame to lay).
We're on the cusp of a pretty big project, and the timeline is severely compressed. We don't feel confident enough in NetWare to support the project long-term...so, unfortunately, for the first time ever, we have to decide between OES (about which we know nothing yet), or Windows Server.
Novell have been sent a series of flares and distress signals (and we are a 'reference' / success-story account)...unfortunately, we've been let down by the sales organization as a whole in bringing focus to our plight.
Good thing my rolodex is filled with the names & numbers of old friends who still roam the Provo halls. With a little luck, we'll get the help we need to translate our significant NetWare expertise to the OES/SLES platform combination.
