The integrated Windows server phase of the installation flags missing information that you did not provide during the i5/OS™ phase of the installation, then allows you to supply the information. This section contains some examples of those error messages and how to respond.
Error (Installing Server)
You may not have specified a value in the To workgroup or To domain fields of the Install Windows Server display on i5/OS. If not, then you will see the following error message:
Error (Installing Server) A setup parameter specified by your system administrator or computer manufacturer is missing or invalid. Setup must therefore ask you to provide this information now. Once you have furnished the required information, unattended Setup operation will continue. You may wish to inform your system administrator or computer manufacturer that the "JoinWorkgroup" value is missing or invalid.
Click OK.
The installation program then prompts you to make the computer a member of a workgroup or domain.
