Windows 2000 Server Limitations

Windows 2000 servers have some limitations, including the lack of bug fixes.

Microsoft Windows 2000 Server was released early in the year 2000 as a significant upgrade to its previous Windows NT line of server products. The most important part of the upgrade was the introduction of Active Directory Domains.

Processors

Windows 2000 Server supports a maximum of four physical CPUs. While dual core CPUs did not exist when Windows 2000 was introduced, it is possible to run Windows 2000 on modern hardware with multiple cores per physical CPU. Windows only counts the physical CPUs, so it is possible, for example, to run up to four dual-core CPUs.

Memory

Windows 2000 Server is a 32-bit operating system and supports a maximum of 4 GB of RAM. When Windows 2000 was introduced, 4 GB of RAM was very expensive compared to today.

Support Limitation

Windows 2000 is considered a legacy operating system and is no longer supported as of the middle of 2010. This means that Microsoft no longer releases security updates and bug fixes for Windows 2000. The only option is to upgrade to a newer version of Windows Server, such as 2003 Server or 2008 Server.
