How do I fix the ERROR_DUP_NAME?
1. Change the computer name
If you’re running an older Windows OS, you can change the PC name from Control Panel > System. Renaming your computer will ensure that you don’t have a duplicate name on the network, thus avoiding the ERROR_DUP_NAME issue.

Usually, if there are no issues, you will receive theNERR_Successmessage. However, if the domain is already on the network, the system will return the ERROR_DUP_NAME message. Of course, you will either have to change the domain name or investigate if the domain is already validated and working.
