You want to view the nested members of a group.
Open the Active Directory Users and Computers snap-in.
If you need to change domains, right-click on Active Directory Users and Computers in the left pane, select Connect to Domain, enter the domain name, and click OK.
In the left pane, right-click on the domain and select Find.
Enter the name of the group and click Find Now.
Double-click on the group in the bottom results pane.
Click the Members tab.
You now have to double-click on each group member to view its membership.
> dsget group "<GroupDN>" -members -expand

As described in Recipe 7.2, group membership is stored in the multivalued member attribute on group objects. But that attribute will not show the complete picture because group nesting is allowed in Active Directory after you've transitioned from mixed mode. To view the complete group membership, you have to recurse through each group's members.
In the VBScript example, I used a dictionary object (referred to as a hash or associative array in other languages) to ensure I did not get in an infinite loop. The dictionary object stores each group member; before the DisplayMembers function is called a check is performed to determine if the group has already been evaluated. If so, a message is displayed indicating the group will not be processed again. If this type of checking was not employed and you had a situation where group A was a member of group B, group B was a member of group C, and group C was a member of group A, the loop would repeat without terminating.
