I'm sorry, but there was wrong information in my previous mail: the database that owns the db_link runs on Windows 2000 Server and the target database runs on Windows 2003 server. We get the same error via sqlplus.

On the other hand, everything runs properly if we connect from the W2003 Server to a database on the W2K Server Both servers are in the same domain. The Active Directory is installed on a W2003 Server.

Do you know if there is any incompatibility, bug, etc. connecting from a W2KServer to a database on W2003Server? I haven't found any information about it.

Thanks again. Received on Thu Nov 08 2007 - 09:14:59 CST
