I've run out of ideas and see forum problems similiar, but not like this. Install guide was following three times letter by letter. Cleaned out and tried a fourth time with same results and went to reasearch mode.

I am doing a Fresh install DNN 4.0.2, from starter kit usuing VS2005 and publish to IIS location configured for .NET2x and has proper permissions in place.

IIS5 Win XP Pro, SQL Server 2005 on a 2003 Server
Installation seems to run OK down to where it installs portals , then it burbs
Trying to go to home page after install results in the following message:

Server Error in '/WxDNN' Application.

Exactly same problem on click to access portal and I see there is another thread with others with same problem. Have you found a solution yet? If so can you post it.

During Installation DNN needs to write to your DNN Application folder. You need to make sure you have Proper file permissions for the ASPNET, Network Service, INET_USR, etc for R/W on that folder.

Can you be a little more specific? Which DNN application folder? I'm installing for the first time, and so far, this is an extremely ugly process....

This is what my installation "log" looks like so far....

--------------------------------------------------------------------------------------------------
DNN 4.0 Setup Issues
---------------------------------------
- installed starter kit
- created new website from VS 2005
- manually changed asp.net version to 2.0 in IIS
- created new DB in SQL 2005
- created new login for SQL 2005: ERRORS
    - 18452: Login failed (solution - change SQL Server to mixed authentication mode)
    - 233: ASP.NET process? No, Named Pipes! (SQL Configuration Tool, Named Pipes turned on), restart
- refer to localhost/{dnn_website_name}/documents/welcome.html
- changed release.config to web.config
** VS 2005 generally REALLY, REALLY slow (eg. changes to web.config, just file access, no rebuild, 30+ seconds saving) **
- changed sql connection string (non-sql express, full 2005) (and in <appSettings> section):
 <!-- Connection String for SQL Server 2000/2005 -->
    <add
      name="SiteSqlServer"
      connectionString="Server=.;Database=dnnstruments;uid=dnnstruments;pwd=webstruments;"
      providerName="System.Data.SqlClient" />
- VS really slow solved: recent projects list manually removed from registry :)  http://forums.asp.net/thread/1184416.aspx
- NTFS permissions added: NETWORK SECURITY, through file explorer, full control, inheritable to all
- rebuilt solution in VS
- ERROR: failed to access IIS metabase, tried:
    - connected to SmithBucklin VPN (b/c aspnet_regiis -ga ASPNET wasn't working
    - then, inheritable permissions for IUSR_WCHI1380 and IWAM_WCHI1380
    - then, ran aspnet_regiis -ga for IUSR_WCHI1380 and IWAM_WCHI1380 (IIS process launch and Internet guest account)
    - where's ASPNET user account?
    - that worked though
- ERROR: mutex could not be created
    - had to do http://forums.asp.net/1109781/ShowPost.aspx
    - basically, close VS, and delete temporary asp.net files from .net 2.0 folder   
- Then got an ERROR: Object reference not set to an instance of an object.
    - http://forums.asp.net/thread/1137232.aspx
    - that didn't help
  --------------------------------------------------------------------------------------------------

I'm running XP pro, sql server 2005, vs 2005, http solution (not file), IIS 5.0.

You can see that I got through a lot of s*** and now this one has just stumped me. Please help me re-kindle my weening faith in DNN.
