You can use attributes to group computers. For example, you can
create an attribute that identifies computers running
Windows 2000. You can then use the attribute to create a
computer group.
To create a computer attribute:
Expand Microsoft Operations Manager (default) in the
left pane.
Expand Rules in the left pane.
Expand Advanced in the left pane.
Click Computer Attributes in the left pane.
Click Action on the menu bar.
Click Create Registry-Based Computer Attribute on the
Action menu.
Follow the instructions until you finish creating a computer
attribute. For more information about the fields on a window, click
