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