Network Administration: Windows Server Default Groups

Windows Server 2008 comes with a number of predefined groups that you can use. Although you shouldn’t be afraid to create your own groups when you need them, there’s no reason to create your own group if you find a default group that meets your needs.

Some of these groups are listed in the Builtin container in the Active Directory Users and Computers management console. Others are found in the Users container.

Default Groups Located in the Builtin Container
Group Description
Account Operators This group is for users who should be allowed to create, edit,
or delete user accounts but shouldn’t be granted full
administrator status.
Administrators These are the system administrators who have full control over
the domain. The Administrator account is a default member of this
group. You should create only a limited number of accounts that
belong to this group.
Backup Operators This group is for users who need to perform backup operations.
Because this group must have access to the files that are backed
up, it presents a security risk. So you should limit the number of
users that you add to this group.
Guests This group allows members to log on, but little else. The
default Guest account is a member of this group.
Network Configuration This group is allowed to twiddle with network configuration
settings, including releasing and renewing DHCP leases.

ability to create and share new printers and manage print
