To delete a local group from a member server or computer running Windows 2000 Professional
WinNT://sComputerName , computer
where sComputerName is the name of the computer group to access.
In the binding string, the ",computer" parameter instruct ADSI that it is binding to a computer and allows the WinNT provider's parser to skip some ambiguity-resolution queries to determine what type of object you are binding to.
You do not need to call IADs::SetInfo to commit the change to the container. The IADsContainer::Delete call commits the deletion of the group directly to the directory.
