donald, please ignore slwslw. He appears to be the forum's latest troll, with a penchant for reviving old threads (although, admittedly, he was the first to answer your rather brief question, so I guess that counts for something).
Background check companies are governed by the same rules and procedures that the credit reporting agencies are. In order to correct errors that appear, you must follow the same dispute guidelines. A civil action against the background check company is possible if corrections are not made in a timely fashion.
