Cross LDAP Domain search - how do I do it?

[dln]

Hello all. Our organization has multiple domains, all of which are part of
the same forest. Using the DirectorySearcher class, how would I specify a
search root that would allow the AD search to span all the domains in the
same forest when looking for a specific user or group (search the global
catalog)? Is this possible or do I need to perform a separate search for
each domain?

Thanks.

Figured it out - need to do a query against the global catalog server.
Thanks anyway.
