Will Windows 2000 Server install over (upgrade) Windows XP Pro? I bought a new server this week, and it came with XP Pro. I didn't know until I had installed the server that only 10 users could connect at one time using XP. We have 13 users, and we were using 2000 Server. It looks as though I'll have to reformat and install 2000 Server, unless I can do an upgrade. Our server is a file server only, we aren't using any Client/Server applications. Has anyone ever tried to upgrade XP Pro with Windows 2000 Server? Does anyone know a workaround to the 10 user limit on XP?
