PLease guys , can you help me solving the error that i posted above.

I followed all the documentation instruction and i have no ideea why o get that error message.

I'm using DNN 4, and ASP 2, i have renamed release.config to web.config.... do i havet to make any changes?

I had to give the IIS user account permission to the IIS database:

Right click My Computer and select Manage, open Local Users and Groups, click on Users: You should see a user beginning with IWAM_ and the description will say "Launch IIS Process Account". This is the user you need to give permission to.

Find the aspnet_regiis.exe on your computer, usually located at C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727

From a command line (Start\Run\cmd.exe) switch to the above folder (cd C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727) and execute: aspnet_regiis –ga IWAM_<your computer name>

At least I think that got me past the error. Note this is for ASP.Net 2. For older versions you'll have to see http://support.microsoft.com/?kbid=267904.
