Tech Tip: Create Setup boot disks/Use round robin DNS

Windows 2000 Professional: Create Setup boot disks

Using Remote Installation Service (RIS) to deploy Windows 2000 automatically is the easiest way to install the operating system. The second easiest ways to install it are running Setup from a bootable CD or performing an installation across the network from a network share. However, in some situations, none of these methods is possible.

In the absence of an RIS server, bootable client OS to access a network installation share, or a bootable CD and system that supports boot from CD, your only option is to use a set of Setup boot disks. This disk set enables you to boot the computer, start Setup, and install the basic drivers and files needed to start the Setup process from the Windows 2000 CD.

Windows 2000 doesn't include a set of bootable Setup disks, but it does include a utility that enables you to create the boot disk set.

Follow these instructions to create a boot disk set for Win2K:

  1. If you're running Windows 9x or later, from the Windows 2000 CD-ROM, run Makebt32.exe A: from the CD's \bootdisk folder (assuming drive A: is the target floppy drive). If you're running DOS or booted from a Windows 9x boot disk, run Makeboot.exe A:.
  2. Follow the prompts from Makebt32.exe or Makeboot.exe to create the Setup disks. The program will prompt you to insert each disk at the appropriate time and will copy the necessary disk image to each disk.

Please note that disks created from the Windows 2000 Server CD will not work for Windows 2000 Professional, or vice versa.

Windows 2000 Server: Use round robin DNS

Nothing prevents an administrator from creating multiple host records that have the same host name but point to different IP addresses. When a Windows 2000 DNS server responds to DNS queries, it doesn't respond with the first corresponding record. Instead, it responds with records in turn, cycling through the matching records in what's known as round robin.

The result of round robin DNS is that one client receives the first host record, the next receives the second, and so on. In effect, round robin DNS points clients to different host IP addresses for the same host name.

Round robin DNS provides a simple mechanism for load balancing between servers that supply the same resource, such as a Web site. For example, if your existing Web server is beginning to experience a relatively high workload, you want to put in another server, duplicate the content, and load balance the requests for the site across the two servers. Using round robin DNS to load balance the traffic is one very quick solution for equalizing server load.

To set up round robin load balancing, create as many host records as needed in the DNS zone for the domain. Use the same host name for each, but specify a unique IP address.
