The AD components can do all this. Oddly, the Get Computer List does not include the DN of the computer (which would give you the info you need). BUT, the Get User Details will, and it works!
The Get User Details component does not care what type of info you are looking up in AD, it will look up any SamAccountName - user or computer. Use that component, and then you can check the DN to see what OU the computer in in. You can then use the Move Object to Container to move the computer where ever you like.
The other alternative is to use the LDAP generator to create a simple LDAP query that gets just the one field you need. But really, that is more work, the Get User Component works just fine.
