 I running into an interesting problem with 5.1.1 (also tried it with 5.1.2) on Server 2003 and 2008. When I install DNN into the default web directory (C:/inetpub/wwwroot) everything works fine, but when I try to install it on a completely different drive letter (in my case I tried to install it on the root of an E: drive I have), I get a NullReferenceException when I click Finish (Go to site).

Server Error in '/' Application.

 So apparently you can't install DNN at the root of a drive, you have to put it into a folder. I just created a folder on the separate drive, installed it into that and everything seems to work.
