Windows vCenter Server 6.5 installation fails while configuring the vAPI EndPoint ServiceOne of the reasons this is a problem (not presently documented by Vmware)
Is because NTLM is being blocked. During my time chatting with Vmware support they hadn't come across this before and don't presently have a fix for changing NTLM to kerberos authentication.
However if you have the option to and capability to:
These are the following fixes.
- Allow NTLM in all forms on your domain.
- Setup vCenter Appliance.
If Vmware come back to me with a fix I'll update the page here.
