I am trying to set up a linked server in MSSQL to an IBM AS400 using the IBM AS400 OLE DB Provider. The New Linked Server dialog box asks for properties Product Name and Data Source. I would like to know from someone who has successfully set up a linked server to an AS400 what the specific syntax in the properties needs to be. I have reviewed the OLB section on sp_addlinkedserver, and while this is helpful and gives many specific examples, I need an example for an AS400. Thank you to anyone who can help!
