Hi ... I'm trying to implement Remoting with an Http Channel, to do this, I add a Remoting.config

file to a WebServer Application and on the App_Start Event I run the following line :

Dim strRemConfig As String
    strRemConfig = HttpContext.Current.Server.MapPath("./Remoting.config")
    RemotingConfiguration.Configure(strRemConfig)

And my Remote Object is started !!

I have a test client, to check the functionallity, and It only works when the Virtual Directory is

configured with an Anonymous Access in the Directory Security Options. (uses the IUSR_XXX user). but

when I change to the "Integrated Windows Authentication" mode I receive the following error:


************** Exception Text **************
System.Net.WebException: The underlying connection was closed: The request was canceled.

Server stack trace:
   at System.Net.HttpWebRequest.CheckFinalStatus()


I also receive a "401 Unauthorized error" sometimes.


Do you have any suggestions to do this ? I want the Integrated Windows Authentication, to propagate

the local logued Windows user and have integrated security in the BackEnd.

Thanks from Spain

Have you tried giving access rights to the Network service (in Win server 2k3) or IUSR_xxx on that folder (not the virtual version).

I'm just guessing here, maybe it's a problem with the extension? Try changing the extension (.config) to another one (like .txt or .xml).

Is the browser prompting for credentials?
If this is IE, does the server name (as typed in the address bar) contain a dot?
Bit of a long shot, but does the server try to use the user's credentials to access a third computer?

Whatever
What credentials are you trying to connect with?
Is it a local user?

Try setting the useDefaultCredentials property on the HttpChannel To True

I try with the DefaultCredentials, but nothing.

I'll try this demo in a diferent scenario to see

Thanks ...

I finally make this work ...

I have to use the useDefaultCredentials=true on a config file, just like Cooler told me.

I put the following code in a Remoting.config file

<?xml version="1.0" encoding="utf-8" ?>

<configuration>

<system.runtime.remoting>

<application>

<channels>

<channel ref='http' useDefaultCredentials='true'>

<clientProviders>

<formatter ref='binary' />

</clientProviders>

</channel>

</channels>

</application>

</system.runtime.remoting>

</configuration>



After this, I configure Remoting to use the config file and load the settings inside the file.

Dim file As String = "Remoting.config"

RemotingConfiguration.Configure(file)



And now it works !!

Thanks to everybody
