We are in the process of migrating from an NT Domain to Active Directory and
have move our SharePoint Portal 2003 to Active Directory. So far so good.

I started an Import of User Profiles before thinking. After the import
reached 1800 records I stopped the import. It was importing profiles from
the AD Forrest instead of from our OU.

Two questions:

1. Is there a way to do a bulk delete of profiles from the database instead
of having to go through 352 pages of profiles and check each one?

2. I tried modifying the search base to include OU's for our subunit and
used this filter from the Resource Kit:
(&(objectCategory=Person)(objectClass=User)(
!(userAccount-Control:1.2.840.113556.1.4.803:=2)))
but it will not take. It throws an error:
A test import based on current input returned no results. Please re-check
the search base and filter.
Where do I go from here?
