From the stables of SharePoint 2007 error-laden blockbuster features, comes another mysterious and annoying error, *drum roll*special effects*camera upclose*camera drawback*more Star War effects*

An exception of type System.Reflection.TargetInvocationException was thrown. Additional exception information: Exception has been thrown by the target of an invocation.

Sounds like something from FRINGE.

This happens when you try to join a new server to a farm. And that is after you have battled the infamous installcheck which returned like 80 language packs problem, 120+ missing locally problem and the rest of the evil minions from SharePain hell.

So, what do we do? How do we resolve?

You won't believe this. It's your NTFS drive letter causing this. Crazy!

Just to be sure, open your ULS log file in the APPLICATION server and do a search for directory name you entered is invalid.

If this returns a series of results (best if you use Notepad++) then that is the problem. What to do is take a look at the drive letter convention in your machines, and ensure your new server is consistent with the drive letters. So, if your APPLICATION server has C, D, E, F drives, ensure your new machine is named the same way. When done, re-run the Configuration Wizard again, and you should be fine.
