A workgroup is a logical grouping of resources on a network. It is generally used in peer-to-peer networks. This means that each computer is responsible for access to its resources. Each computer has its own account database and is administered separately. Security is not shared between computers, and administration is more difficult than in a centralized domain. A workgroup is only intended as a convenience to help find resources. When browsing the network, the resources in your same workgroup are found first. It does not provide any security. In a workgroup, you might have to remember a different password for every resource you want to access. To join a workgroup during installation, all you need is a workgroup name. This can be the name of an existing workgroup or a new one. You must join a workgroup or a domain during installation, but you can change these memberships later as needed.
Windows 2000 Professional Application Compatibility
In addition to determining that your hardware is compatible with Windows 2000, you should also verify that your software is compatible with Windows 2000. Most applications that were compatible with Windows NT 3.51 and 4.0 will be compatible with Windows 2000. Since Windows 95 and 98 were compatible with MS-DOS applications, some applications that ran on Windows 95 and 98 will not be compatible with Windows 2000. This is especially true for older programs that accessed the hardware directly. Windows 2000 does not allow the hardware to be accessed directly; it must be accessed through the operating system. This was also true in Windows NT. Prior to upgrading to Windows 2000, you should remove the following types of applications:
- Any third-party Plug and Play tools. These are no longer needed, since Windows 2000 is now Plug and Play compatible.
- All third-party network protocols and client software. However, you can look on the CD-ROM in the i386\winntupg folder to see if there is an update for your networking software. If there is, then you can leave your software installed.
- You should remove antivirus software and any third-party disk quota software because of the changes to NTFS. It needs to be compatible with NTFS 5.
- If you have any third-party power management software, you should remove it, because Windows 2000 has changed its power management support.
