ESX/ESXi Copy Paste not working, ESXi Isolation issue

I several posts and guides I found that there is an issue that seems to be correct configuration of vmx file do not enable copy paste functionality, I finally figured out the issue.

Requirement

Enable Copy ans Paste between Virtual Machine and remote User Machine, given that VM is hosted on VMware ESX/ESXi server.

Even setting following properties in .vmx file it wont enable copy and paste

isolation.tools.copy.disable = "FALSE"

isolation.tools.paste.disable = "FALSE"

Solution

In most of the websites they do not mentioned case sensitivity requirement, for example ESXi 5.5 must required false in lower case, therefore correct property should be

isolation.tools.copy.disable = "false"

isolation.tools.paste.disable = "false"
