Service Account changes after Upgrade

I’d like to report something that seemed to happen after we upgraded the server to the new release. It appears that the service account changed to the words “Local System” and overwrote our domain service account. We became aware of this when we noticed errors in the logs related to source directories being “not found”.

I have attached a screen shot

Thank you, Bruce. We will investigate why this is happening.
