Bardaris asks: "In my work environment, I maintain a large number of Novell, and Windows servers. Although Novell is the dominant OS, vendor applications are increasingly making the change from Novell based apps, to single NT4/Win 2k servers. This has put a strain on my PDC. Currently the MS boxes are outnumbering my Novell 30 to 22, with more Win 2k servers in the coming months, as each application vendor has found it cheaper to dictate a sole Win server for their app, rather than sharing nicely on Novell. Now I've been tasked with assessing what to do with the Windows environment. My preference leans to eDirectory and dirXML to contain and maintain the Microsoft proliferation, but what of my NT4 PDC. Should I upgrade to Active Directory (if so, how)? Leave it as is until the last possible moment, whatever that may be? Is there a better way? I highly doubt I can sell a Linux/Samba solution, given the current state of the server environment and political climate here in my company, so that's not one of my options. I'm wondering if other Slashdot readers have ran across similar problems and how they tackled this issue."
