Why does the server service fail to start with the message “The AtlasService service cannot be started on this computer”?

Problem:

After an update, the following message appears when attempting to start the XPhone Server

Solution:

To resolve this issue, temporarily switch the service account to LocalSystem and then switch it back to the original service account. The server should now start as usual.
