I figured it out with your help. Thank you for your help.
I am not sure why the code changed after I changed the AD username/password in fog settings, because it seems the host continued to use the original. This was seen under the host->active directory. I added all 50 computers to a group and changed the setting for the group which changed the settings for all 50 hosts. It seems like the global setting should have done this, but it didn’t.
