I downloaded DotNetNuke_04.05.03_Install.zip today and attempted a new clean install.

I am using IIS 5.1 and SQL Server 2000

I have extracted the file to C:/DotNetNuke. I then changed the Web.config file to point to my database. I set up IIS with a new virtual site and pointed IIS to the C:/DotNetNuke directory. When i then visit http://localhost I get the Server Unavailable error.

My error logs say:

WARNING:

System.Web.Hosting.ApplicationManager.CreateAppDomainWithHostingEnvironment(String appId, IApplicationHost appHost, HostingEnvironmentParameters hostingParameters)
   at System.Web.Hosting.ApplicationManager.CreateAppDomainWithHostingEnvironmentAndReportErrors(String appId, IApplicationHost appHost, HostingEnvironmentParameters hostingParameters)

ERROR:

Failed to execute the request because the ASP.NET process identity does not have read permissions to the global assembly cache. Error: 0x80131902

ERROR:

aspnet_wp.exe  (PID: 4848) stopped unexpectedly.

Any point in the right direction would be helpful.

Thanks!

From the error it looks like the asp.net proccess does not have all the permissions.

Give the ASPNET (WinXP) or Network Service (Server 2003) account Read, Write, and Modify permissions on the directory you unzipped to.
