Windows Server (2016/2019) is a stripped down version of server operating system. Since its a stripped down version, There is no graphical interface for this servers. So installing any software on this servers might be bit tricky.
Windows server core in ESXi/Vsphere virtual machine with VMware tools. But its recommended to have up-to date VMware tools installed to utilise advanced features.
Let see how to install tools without graphical window.
I have a Windows server 2019 core VM, No VMware tools installed.
1. Login to ESXi or Vcenter web console, Mount Vmware tools CD ISO image by selecting Gues OS > Install VMware Tools.
2. Launch VM console or access Server using RDP. Run DISKPART command in command prompt.
Execute " List Vol" Command in DISKPART prompt to identify VMware tools CD driver letter.
In my case its Volume 0 and Drive "D".
3. Exit from DISKPART and change directory to E drive.
4. Run Setup.exe from command prompt.
5. This will start " VMware Product Installation" graphic window.
Note : Sometimes setup window might be hidden behind command prompt window. In that case minimise command prompt windows, Now you should be able to see setup window.
