We have a VM running Win10 Enterprise (vSphere 5.5) which VMware Tools often switches between "Not running (Current)" and "Running (Current)". I'm guessing that whatever is causing this issue is also causing users to not be able to RDP into the VM and also causing errors when running a nightly backup.
Thanks
How old is the 5.5?
vSphere Client 5.5.0
Build: 2067769
