I was adding a new web front end (WFE) server to a farm last week and ran into this error while running config wizard.

Task configdb has failed with an unknown exception

After some poking around the net I found that my buddy Eric Shupps had seen this error before also. http://www.binarywave.com/blogs/eshupps/Lists/Posts/Post.aspx?ID=139 The issue stems from the fact that WFE1 had the usage logs set to go to the D:\ drive in Central Admin. When config wizard tried to provision this folder on WFE2 it errored out because the server did not have a D:. Whoops.

Thanks Eric!
