JSI Tip 7619. When you create a trust using Active Directory Domains and Trusts, you receive 'Operation failed. Parameter incorrect'?

The subject behavior will occur if any of the following identifiers in the source and target domains are the same:

Security identifier (SID)
Domain Name System (DNS) name
NetBIOS name

To fix this problem, perform the appropriate action from the following list, before you try to create a trust:

• If there is a NetBIOS conflict, use the FQDN (Fully Qualified Domain Name).

• Rename the identifier that is conflicting.
