Welcome to the communities.
Its good to know that problem has been resolved ,
I have gained few experience problem getting resolved after installing hot fix and few tools.
Ok. But does vm,ware tools can cause server reboot at regular intervals..
i dont think so.....
Still figuring out what might have caused windows server 2012 to reboot at regular interval.

I had this same problem if you do a full installation of vmware tools it installs the vShield driver which caused my Windows 2012 servers to randomly reboot several times a week. I actually had to view the windows dump file using WinDbg to find that the crash was caused by a memory leak with the vShield drver. So, if you remove the current install of tools and just do a typical install, yes it would solve your problems because that driver does not get loaded on a typical install. Also with ESXi 5.5 Update 2 the vShield driver is not packaged anymore with tools, so it shouldn't be an issue going forward.
