I purchased an NX3000 from Dell in Feb. 2010. My first goal was to move engineering drawings from our overloaded Proliant server to the new machine running Windows Storage Server 2008. Problem was that the engineers needing access to the drawings were running XP 64-bit, which is incompatible with Storage Server 2008, they couldn't see more than 19 folders in a subdirectory on the server, or more than 19 files in any directory on the new server. So I rebuilt their machines in 32 bit, no big deal. Now I have moved a bunch of sales files to the new server, and 2 different programs are unable to open files, giving a "file not found" or "file is corrupt" error message. Granted one of the programs is old (16-bit), but the other is the latest version available. Dell says Microsoft only tested the 2008 Storage Server OS with Vista and Windows 7, I am running 82 XP Pro SP3 machines. Dell cannot give me a solution, Microsoft doesn't seem to care. So I am ready to punt and install Server 2003 Standard on this machine. Has anyone done this? Should drivers be available for the unit? Dell says the warranty will be void if I do that, but I am at my wits end. Any suggestions welcome.
