I have an InterBase 5 database, which has been registered as an ODBC System Data Source in my Windows 2000. When I try to add it as a linked server in SQL server 2005, the Add Linked Server page make me so frustrated. I can select the ODBC driver, but I don't know how to specify values for the fields such as Product Name, Database Source, and Provider string. I tried many combinations on these field values, all unsucceed. Anybody can tell me how to determine the values of these fields? Any reference articles about this? Please help me!
