I'm trying to join a Windows 10 Professional machine to a Synology Active Directory Domain. I've reloaded Window 10 Pro several times and continue to get the same results.
I'm getting the following messages:
The join operation was not successful. This could be cause an existing computer account having name "ABCES" was previously created using a different set of credentials. Use a different computer name, or contract your administrator to remove any stale conflicting account. The error was: Access denied.
In the above case I've used several different computer names and continue to get the same message. I've been able to join other non-Windows machines to the Domain with no issues.
I've also tried joining the domain using the "Network ID" button and I get the following message:
Your computer could no be joined to the domain because the following error has occurred: This user can't sign in because this account is currently disabled.
In this above case the account used to join the domain is not disabled or lock in any way that I can see.
What am i doing wrong or what could be causing this to occur? All of the latest service packs have been applied. Running Windows 10 Version 1901 (OS Build 18363.1379).
