@Bigredcherokee I have seen people in the past “think” they can use this account for system administration, they install FOG and the installer takes over this account and gives it a new password. The admin then resets the password on the fog account that’s where things usually go sideways. FOG will throw a similar error to what you last posted when this happens.
You will also see a similar error when you try to capture an image. Right at the end of the capture it will fail with an error about unable to update the fog database. That is an indication that the fog service account’s password has changed.
