- You are trying to use the logon.dbc from another computer on a new computer and you are asking about the Password field and the information needed
You do not need to put anything in the Username or Password field. When you go into the ATLAS SQL Alias Manager, you will need to right-click on the Shortcut and "Run as Administrator." If you have both the Username and Password field in the LOGON.DBC, then you need to open the file that they put in the c:\program files (x86)\ILLiad folder and Save it. Then click on the "Set Default" icon. You will get a message that the file is "Set as default" and where it is. You choose, "OK." They should be able to log on to ILLiad.
If you have ILLiad as the Username and no password in the file you sent to another person to put on their computer, then they need to remove the Username and save it. Click on the "Set Default" icon. What happens in the background is that when you save the information, and there is no Username or Password in the system, ILLiad puts in the Username and Password. They would see the fields filled in with the first example above. In the second one where they remove the Username, they will not see the fields change, but if they close the ATLAS SQL Alias Manager and open it up again, the Username and Password will be there.
Information about this is in the documentation for the Atlas SQL Alias Manager.
