VBScript: Search for and Enumerate an OU

I have an extremely large AD environment and have a need for a script that I can run, that would accept an OU name (ie: Indy) as input, search for that OU and then return a list of users for that OU.  The users part I can do, but I'm stuck with finding the OU portion.  I figured ADO is the best/quickest method but not real experienced using ADO. 
 
Can anyone get me started?  Thanks in advance

Try running a query with scope "subtree" and LDAP filter "(&(objectclass=organizationalunit)(name=Indy))" on the domain root.
