SQL Server four-part names

I have a linked server setup in SQL Server 2000 that points to my Informix database. I am successful in querying data from my Informix data source when querying with a pass-through query: SELECT MyTable.* FROM OPENQUERY(<linked server name>, 'SELECT * FROM customers') MyTable I have not been successful in querying data with a four-part name using this syntax: SELECT * FROM <linked server name>.<data source name>.<owner>.<tablename> I receive the following error when I attempt to query using this SQL statement: OLE DB provider 'MSDASQL' reported an error. [OLE/DB provider returned message: Unspecified error] [OLE/DB provider returned message: [Informix][Informix ODBC Driver][Informix]Database not found or no system permission.] OLE DB error trace [OLE/DB Provider 'MSDASQL' IDBSchemaRowset::GetRowset returned 0x80004005: ]. I am certain that the user account I am using to access the data source is sufficient and I am certain that the table name is correct. Perhaps my database owner is wrong? How do I obtain this information? Any other suggestions? Thanks in advance. Scott Adams I <> "The Dilbert Guy" AND I <> "Writer of the Adventure Series"
