Join problem client to the DC
Geetings,
Customer setup a antivirüs program and happened some problems. We delete it and restore the computer healy working point. First of all I had a joining fault of the client to the domain controller normally(2 DC+AS+Connectivity+10 client). I release client from domain and add againt the domain problem solved.
Now client opeining but red padlock appeared right bottom side of the computer. And workplace comes with empty box only alarms come. I remove client from disconnecting. Now I how to add this client. Add node or other node adding do not have in configuration wizard. May I remove this client and add again or another way to solve this? I added picture of screenshot. Why this red padlock apperes instead of normal gray configuration wizard icon.

Run the "System Software User Settings" on the clients.
The red padlock appears because the accounts used to run the 800xA system services are now invalid. You broke them when the client left / rejoined the domain. Even though the account names and passwords are the same, the Windows indentifiers changed. Windows does not recognize the accounts any more.
