Do you know the name of the computer? Generally, you are going to write an
LDAP search filter for this that would go something like:

(sAMAccoutName=xxxx)

Where xxxx is the name of the computer you are looking for. sAMAccountName
is unique on the domain for all objects and is indexed, so this will find
the computer in any container and will be fast.

You also need to specify a root for your search which will probably be the
defaultNamingContext of the domain. You can get this dynamically by binding
to RootDSE with IADs and getting the defaultNamingContext attribute.

If you don't know the computer name, tell us what you do know.

I also highly recommend using MS's ldp.exe tool for modeling LDAP searches
against AD. It comes with the server support tools or the ADAM install.

HTH,
