What is required:
-RIS server:
Chances are that the image that you have prepared from the CD in the previous step will be missing drivers for the network card that is in the PC that you are attempting to install. You would get this error message: “The operating system image you selected does not contain the necessary driver for your network adapter” Follow this KB article to add the drivers into the installation image: http://support.microsoft.com/default.aspx?scid=kb;EN-US;246184 after doing that do not forget to restart the RIS server:
net stop binlsvc net start binlsvc
At this point you should be able to boot and connect to the RIS server, but you still may get BSD: STOP error 0x000000bb, one of the reasons for this maybe that your client is using duplicate IP address, check your DHCP and addressing.
This step is necessary only the first time when you are creating the first image. Following images are automatically added to the RIS server. You can use this procedure to view and modify the descriptions for the installed images and to remove images.
