We have MDAC 2.8 SP2 installed a SQL2000 server with iSeries client access. We are getting access denied when we attempt to access iSeries linked servers. I have recreated the same linked server on another SQL2000 running MDAC 2.8 SP1 (2.81.1124) and the linked server works fine. The iSeries is v5.2. As a workaround, I have create a system DSN to the iSeries and used it in the linked server and this works fine. Any ideas?
