NT AUTHORITY\NetworkService Access denied

I am having a problem with sharepoint services and sqlexpress.  My system was running just fine, and I did a dcpromo to make the system a DC.  Now, the SQL services will not start along with Sharepoint service.  
The sharepoint and sql are configured to run on NT AUTHORITY\NetworkService.  

I get the following errors in event viewer

I looked for the NT AUTHORITY\NetworkService in the directory but can not find it.

Any ideas?
