I have followed the procedures to run Setup Manger by STEP-BY-STEP_PREINSTALLATION_OEMS.doc which is located on the DOCS\WHITEPAPERS of Disk Windows XP OEM Preinstallation Kit. In the winbom.ini made by the Setup Manger, I have added Ipconfig=169.172.0.2 and Subnetmask=255.255.0.0 to configure peer-to-peer preinstalllation. There are 5 steps in Factory Preinstallation: I have passed: 1. Setting display resolution 2. Partitioning disks and formatting drives 3. Starting networking But failed at the fourth step 4. Installing the Configuration Set In winbom.log, there are these two messages, ERROR: Cannot authenticate to server: Incorrect function. ERROR: Factory state "Installing the Configuration Set" failed. I have shared the directory of OPK Tools as Distribution Share, Username = opkuser and Password = "opkuserpassword". In addition, for the preinstalled application, I have specified network access credentials with Username = appuser and Password = "appuserpassword". Could you provide your advice and suggestion in solving this error? Best regards, Rudiger
