First let me say thanks to the community so far for helping me get this site up and running properly.  Without your help I would not have any hair or sanity left.

Setup: I am using DNN 4.02 and SQL 2000 DB (DB is on another PC not that it matters)

Server: Windows 2k3 Standard

I have gone to web.config and made the following change per other posts.

<httpModules>

<add name="Authentication" type="DotNetNuke.HttpModules.AuthenticationModule, DotNetNuke.HttpModules.Authentication" />

<add name="UrlRewrite" type="DotNetNuke.HttpModules.UrlRewriteModule, DotNetNuke.HttpModules.UrlRewrite" />

<add name="Exception" type="DotNetNuke.HttpModules.ExceptionModule, DotNetNuke.HttpModules.Exception" />

<add name="UsersOnline" type="DotNetNuke.HttpModules.UsersOnlineModule, DotNetNuke.HttpModules.UsersOnline" />

<add name="DNNMembership" type="DotNetNuke.HttpModules.DNNMembershipModule, DotNetNuke.HttpModules.DNNMembership" />

<add name="Personalization" type="DotNetNuke.HttpModules.PersonalizationModule, DotNetNuke.HttpModules.Personalization" />

</httpModules>

When I go to Admin and the Authentication I select the following

X for Windows Authentication

X for Sychronize Roles

Provider: ADSIAuthenticationProvider ( No other options available)

Authentication Type: Delegation

Root Domain: DOMAIN (this is the domain name not the domain controller)

username: (DOMAIN\username)

Password: Standard password for account

Confirm Password: Confirm standard password for account

Email Domain: @DOMAIN.com  ( have tried leaving this blank as well)

This is the error I recieve:

Error: Windows Authentication is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at DotNetNuke.Security.Authentication.ADSI.Utilities.AddADSIPath(String Path, Path ADSIPath) at DotNetNuke.Security.Authentication.ADSI.Utilities.GetRootEntry(Path ADSIPath) at DotNetNuke.Security.Authentication.ADSI.Utilities.GetRootEntry() at DotNetNuke.Security.Authentication.ADSIProvider.GetNetworkStatus() at DotNetNuke.Security.Authentication.AuthenticationController.NetworkStatus() at DotNetNuke.Modules.Authentication.AuthenticationSettings.cmdAuthenticationUpdate_Click(Object sender, EventArgs e) --- End of inner exception stack trace ---

Any assistance would be helpful.  I do not wish to purchase a 3rd party module as our company is doing this on a budget.

Thanks for any assistance anyone can provide.

Rey,

I know this won't help you, even though I can't update the ADSI settings my authentication is working against AD. I'm not sure how that is. For reference should any core members see this, the problem seems to be in the AuthenticationController class.

Private Sub cmdAuthenticationUpdate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdUpdate.Click
...

   Dim objAuthenticationController As New AuthenticationController
   Dim statusMessage As String = objAuthenticationController.NetworkStatus

While debugging the call to the NetworkStatus function results in a NullReferenceException. Oddly enough the objAuthenticationController object itself is not null. Using the quickwatch I can make a call to the GetDNNUser function and the GetStatus function and those both return valid results. For whatever reason I don't seem to have the source code to step into the NetworkStatus fucntion to provide any further insight. Perhaps someone on the core team might. Or atleast point me to why I can't step into that function call.

I don't seem to experience this problem on my production site, just on my development site which was a FRESH 4.0.2 source install with a clean SQL Server 2005 database.

Hopefully someone can pick this up from there.
