Active Directory issue

I have no thoughts on how to search this on google so that's why I'm posting here. There’s something up with the AD. Recently added computers aren’t showing up in the Computers OU (this is actually happening with random computers -- not all). And I can’t find some users at all in the OU they should be in. But if you do a search of that user or the computer you added, you’ll find them in the search results. If you look at their properties, you'll see what they are a member of and that reflects where I'm looking but they're not found in that location? Anyone have a clue on what's going on here? Here's an edited screen shot showing what I'm talking about with a user account. [att=1] -- Insert thoughtful/witty/meaningful/poetic/funny/deep/rude/stupid/random/comment here.
