vSphere 6.x- Unable to use Customization Template

Today I ran into an issue with an old template which I hadn’t used in quite some time. A vendor requested that we spin up a Windows Server 2012 R2 server for testing purposes.  Upon provisioning the server I came across this error message when the old template was selected.

The public key in the specification does not match the vCenter public key. You have to renter the password in order to proceed.

To resolve this issue open vCenter using the vSphere Web client. Select Policies and Profile find your template and select Edit.


Select Administrator Password and reenter the password.
