Helix failure `EPT_S_NOT_REGISTERED`

We've been seeing a lot of Helix runs fail with a number of messages related to EPT_S_NOT_REGISTERED:

System.ComponentModel.Win32Exception : The Local Security Authority cannot be contacted

System.Security.Cryptography.CryptographicException : There are no more endpoints available from the endpoint mapper.

The failures only occur on Windows and inconsistently affect subsets of the IIS, HTTPS, Data Protection, and Certificate tests.

AFAICT, EPT_S_NOT_REGISTERED indicates that lsass.exe is not available.
