When you start a Remote Install Service (RIS) client by using the Remote Install boot disk you created with the Remote Boot Floppy Generator (Rbfg.exe), you may receive the following error message:
Error: Can't resolve IP address address of the DHCP server
Press a key to reboot system.
This problem can occur in either of the following circumstances:
The default gateway (router), defined in the Dynamic Host Configuration Protocol (DHCP) lease (option 3) is unavailable.
The Remote Boot Floppy Generator client is ignoring the subnet mask. This may cause the client to not be able to reach the RIS server when the RIS server is on another subnet in a subnetted environment, or when the RIS server is on the same network in a supernetted environment.
A supported hotfix is available from Microsoft. However, this hotfix is intended to correct only the problem that is described in this article. Apply this hotfix only to systems that are experiencing this specific problem.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Windows 2000 Service Pack 2.
The RIS client disk always communicates through the default gateway (if the default gateway is configured) to connect to RIS. This occurs even if the RIS and DHCP server are on the same subnet that the computer is on.
However, this is not true for computers that support Preboot Execution Environment (PXE) in BIOS or Boot ROM.
Only certain PCI-based network adapters are supported currently and they are listed in the Rbfg.exe utility that creates the boot disk. This utility is in the %Systemroot%\System32\Reminst folder. Click Rbfg.exe, and then click the adapter list button in the Remote Boot Disk Generator screen to see the supported adapters.
You cannot add additional network adapters to the RIS Boot disk. Microsoft adds additional network adapters over time and makes the updates in the Rbfg.exe tool available through typical distribution channels, such as the Internet, Windows Update, and future service pack or feature pack updates.
