I recently bought a small server (Dell T420). Installed Server 2019 Datacenter on it. But I have some questions about setting it up for my small company. I have 3 workstations (in the office with the server) & 1 workstation at a different location that would need to connect. I would like it to hold all company files, run my Quickbooks & other programs I use. Here's my questions: I would like to use the machine as a workstation also? Can I run Windows 10 on this server? (say in a virtual environment like the built-in Hyper-V or another software like VmWare)? Or is this not advisable? Should I set up a VPN for my network? If so, should I just use the VPN settings inside of the Server 2019 software? Or use a third party VPN service? Should I use an FTP Server? Would this be used instead of a VPN? Is the security within the software sufficient? I need to make sure that this network is secure. I am fairly good with Windows OS, but still learning the server stuff. Thanks in advance for any help that is provided.
