If you can't find it in the knowledge base, you should check out the DreamHostSupportForum. Perhaps the answer is there, or else you can post it. There are lots of helpful users around to answer you quickly. If that fails too, then ask the DreamHost support people. They always have an answer for you within 24 hours, but these other choices might be faster.
