Windows 2000 Server needs its space

Find out why Windows 2000 Server requires so much free hard disk space. You'll also learn best practices for installing the OS in your network.

Windows 2000 Server requires at least 1 GB of free hard disk space. The exact amount of space depends on many things, from the number of server components you choose to the files system and the amount of memory you install.

Windows 2000 automatically calculates the size of the page file by multiplying the amount of RAM by 1.5. For instance, if you have 512 MB of RAM, the page file will be around 768 MB. In this case, you'll need at least 1 GB and 768 MB for the OS. Of course, you can place the page file on another partition. Since you'll also install applications on your server, you need at least 4 GB for the OS (not including any applications). The best practice is to install the OS on one partition, applications on another partition, and user data on a third partition.

If you're wondering why Windows 2000 uses so much space, check the system folder. You'll notice the Driver Cache file, which includes the Driver.cab file. This file stores all the drivers and allows you to plug in the devices. The OS will then install the correct drivers automatically.

Another folder that requires a lot of space is DllCache. This folder stores backup copies of all important system files and works together with Windows File Protection (WFP). If you or a program deletes or modifies a system file, WFP will restore the original system file from the DllCache folder.

Even though you could delete the system folder and the DllCache folder and save around 400 MB of space, Microsoft doesn't recommend it.
