I am running this piece of code to get the source code (as string) of my webpage.
The problem is why this function returns 404 error?
Private Function getPageSource(ByVal URL As String) As String
Dim webClient As New System.Net.WebClient()
Dim strSource As String = webClient.DownloadString(URL)
webClient.Dispose()
Return strSource
End Function

this is a bit of a strange one. have my front page of my intranet site and I am trying to pull an RSS feed from a subdirectory forum.
Root
Default.aspx
--->Forum
--->Rssfeed.aspx
On my default.aspx I can pull RSS Feeds from the BBC or any other external website so my code is working fine but when I try and pull a RSS feed from my local server I get "The remote server returned an error: (401) Unaithorized".Now, if I go to the Forum directory within IIS and change the directory secutiry from "Integrated Windows Authentication" to "Enable anonymous access" the RSS comes through to the front page without any errors, however, the forum requires "Integrated Windows Authentication" to be enable to that my users can post on the forum. If I turn both on then Windows authentication is still ignored for my users when they visit the forum.I have hardcoded my credentials in to the Default.aspx.cs to see if that helps but I still get Unauthorized message.My code is here:

As you can see I have tried a couple of different ways to get the credentials to work, it just seems to ignore my credentials and I have full admin access to the server and when I visit the forum it picks up my username.
The following error is coming :

why I'm getting this error? I just re-created (not migrated) my app that was in ASP.NET 1.1 to ASP.NET 2.0. Whole app works perfectly. The only problem I'm getting with this piece of code for the Web Services. I'm running both versions at the same time side-by-side and it works fine in 1.1 and doesn't work in 2.0.

Bam! Error! The remote server returned an error: (500) Internal Server Error.
In IIS we have a virtual directory (named as "Documents") with in application virtual directory (named as "Reference") that points to an shared folder.All the files with in the "Documents" folder are listed and opened by the user (by clicking on the file name) with in the application
"Reference" application runs under an application pool. This application pool is configured to run with an Active directory account. This AD account has been granted write and modify permissions on the shared folder that contains the html files.
When user tries to open any of the html file located with in the shared location from the application following error is thrown.
System.Net.WebException: The remote server returned an error: (500) Internal Server Error
I tried to browse to the location manually and I can see the required files there.
These files where accessible from our application until yesterday. But we started encountering this error from today.
Is there any IIS settings that needs to be modified?

I have a WCF Service that I have boiled down to next to nothing because of this error. It is driving me up the wall. Here's what I have now.
A very simple WCF service with one method that returns a string with the value, "test".
A very simple Web app that uses the service and puts the value of the string into a label.
A web server running IIS 6 on Win 2003 with a SSL certificate.
Other WCF services on the same server that work. I publish the WCF service to it's https location I run the web app in debug mode in VS and it works perfectly. I publish the web app to it's https location on the same server the WCF service resides under the same SSL certificate I get, "The remote server returned an error: (403) Forbidden" I have changed almost every setting in IIS as well as the WCF and Web apps to no avail. I have compared setting in the WCF services that work and everything is the same.
Below are the setting in the web.config for the WCF Service and the WEB app: It appears the problem has to do with the Web app but I am out of ideas.

[code]...
This code is working fine in my local system but when i upload it on server then it gives this error. From the last 1 year it was working fine but from last few days it gives me above said error, please suggest me is there any authentication required to send mail from server (my hosting plan is with 1and1.com)
writing a web Service and one of its web method, I want it to download a png file in form
of buffer from remote server. And My consume application will write that buffer retured by Web service in to file on User's Computer.
However, I am able to do this using Local Web Service but when I published that service on my web server, I always get null retuned
And even in one of my test code while copying file from that server , I always get Access Denied.
Following things I have done for above issue.
1] I even tried making the Anonymous user for the web service the system administrator (with the correct password), to no avail.
2] I also tried sharing out the folder I'm pulling files from to allow access from Everyone.
[Previously same service was working fine on another remote server with IIS 7.0, we checked server IIS Settings but in vain.]
if you know where we are mistaken guide me to resolve this issue as its very urgent.
While running an app from the server where it is deployed the website works fine, however when trying to access it from a different machine(placed in same network), using the same credentials, it shows that I am not an authenticated user.
[code]....
Some of my users are getting the following error
HTTP 502 Proxy Error - The size of the response header is too large. Contact your ISA server administrator. (12216) Internet Security and Acceleration Server
I am guessing it has to do with the size of hidden "__ViewState" tag in my ASP.NET pages.
I also realize that this is restriction imposed to by IT on the users end and I have no contol over it.
I disabled ViewState on all the controls in my ASP.NET pages. However, __ViewState is still generated very large (as always) to persist control-state (e.g. checkbox, radiobutton, etc.)
We have nearly completed an ASP.NET MVC web application running with SSL in IIS and now find that we must integrate with a third-party product that is supplied as a PHP web app running under lightppd on an alternate port, but still on the same server.
We want to make the integration appear as seamless as possible, so our initial strategy is to do all of the authentication through our application, implement a reverse proxy to expose selected features from the third-party product, and then set-up the third-party product to only be accessible from localhost and (if we can manage it) only from the user our app pool runs as. As a second layer on top of this, we plan on running the third party active content in an IFRAME, so we can surround it with our menus and headers. With the right fonts and colors, hopefully, it won't look grossly out of place.
First question: Is this strategy totally naive? Given the hand we've been dealt, is there a better one?
Second question: What is the best way to implement the reverse proxy? I was thinking of using a routing rule with an Http Handler that invokes our usual authorization just as a controller would and makes the requests to the other site, streaming out the results it receives. Is there something that already does this generically, that I can just hook up and invoke? Maybe some way to specify a controller to handle everything I need to proxy and then use a ViewResult that represents a call to an external URL I construct from the URL I received?
If I can get a few pointers on what to look for, I can trot off to the docs for the details.
We want to use a "proxy user" to connect to an LDAP server (Active Directory, Novell, or otherwise) and then make sure that the user trying to log into the application has typed in an acceptable user name and password. I have got the code for connecting to LDAP just fine, but I'm at a loss as to how to check the user name and password. Can you do this through an LDAP query?
Here's the guts of my code so far:
Public Function Authenticate(ByVal UserName As String, ByVal Password As String)
Dim LDAPServer As String = ConfigurationManager.AppSettings("LDAPServer")
Dim proxyUsername As String = ConfigurationManager.AppSettings("LDAPProxyUser")
Dim proxyPassword As String = ConfigurationManager.AppSettings("LDAPProxyPassword")
Dim entry As DirectoryEntry
entry = New DirectoryEntry(LDAPServer, proxyUsername, proxyPassword)
'This performs the LDAP authentication'
Dim obj As Object = entry.NativeObject
Dim search As New DirectorySearcher(entry)
search.Filter = String.Format("(SAMAccountName={0})", UserName)
'How do I check the password now?'
Dim result As SearchResult = search.FindOne()
If result Is Nothing Then Throw New Exception("Unable to find SAMAccountName")
I am using Sql Server 2008 to connect to a Remote Server. Everything was working fine for the last couple of months, and i was successfully connecting to the remote server. Today it suddenly stopped connecting to the remote server. note that i did not alter any configuration settings. Did my isp block Sql Server. My ISP is using ISA SERVER? The error details are:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.

But today nothing is working.
