Hello All.
This is a fresh installation on a Win Server(SMB) 2003 SP2 running IIS 6.0.  Am trying to install the community version of the DNN and it is just not working.  I have the requirenments (SQL 2005 Express, MS .Net).

I have copied all the extracted files to C:\inetpub\DNN, from ISS made virtual dir in the website labeled DNN, have all the required rights, I think I do.......this is what happens.  From IIS I navigate to DNN\Install Directory and right click to browse Install.aspx.  I get this error.  From what I am reading in the materials the installation and initial configuration should work with SQL express no need to modify,  but for some reason I think my problem is even before that......so if any body can point me to the right direction please do,  my brain is very tired after a day or so..........

Server Error in '/DNN' Application.
