Get all groups from a particular OU

Use dsquery:
dsquery group "ou=SomeOU,ou=SomeOtherOU,dc=your,dc=domain,dc=local"
Among othger things, you can as well specify the output format using -o, and you can specify the scope to search using -scope.
Check "dsquery -?" or http://technet2.microsoft.com/windowsserver/en/library/46ba1426-43fd-4985-b429-cd53d3046f011033.mspx?mfr=true for details

Any help....

The dsquery command above will "get all groups from that OU".
You need to be more specific if you requiore more help.

Hi OBDA,

I have a primary and a secondary domain.

EX: Root is "All" and below it is "development".

When ever i run any query it fetches all the details from the development domain not the All domain.That's the reason i wanted a way to be specific .where we can mention the OU and DC.

As in the example above; dsquery expects the node to start its search as argument:
dsquery group "dc=development,dc=all,dc=local"
or whatever.
You can specify the server or domain to query as well using the -s or -d switch; check the link above for details.
