I am trying to execute this command from a web application on sourceServer:
var mgr = ServerManager.OpenRemote(destServer)
but I receive this error:
UnAuthorized access wth a detail error: "Retrieving the COM class factory for remote component with CLSID {2B72133B-3F5B-4602-8952-803546CE3344} from machine failed due to the following error: 80070005"
I have full administrative rights on both servers.
I can issue that command from a console application no problem, but when I try it from the web application, I get the error!
I have tried enabling the remote management checkbox and started teh remote access auto connection manager and also tried updating the load user profile on the applicaiton pool from false to true.
I have searched so much to the point that all of my links are pink in color!
Any input is greatly appreciated.
I've decided to ditch the use of ServerManager.OpenRemote() and use the DirectoryEntry way:
DirectoryEntry root = new DirectoryEntry("IIS://server/W3SVC", username, password)
it is much simpler and straightforward.

I'm getting the following error when attempting to run DotNetNuke 7.1 from IIS.

I've tried running it from Visual Studio 2012 after downloading and extracting the source code to a folder, then running, but I get the same error (also, VS loads about 13 instances of it's built in webserver which can't be correct).
Clearly, there is something wrong with the database. From what I've read in the past, there should have been a start up configuration page (for configuring settings the first time you run the project).
I did look at the local version of IIS (running on Windows 8) and it created the site fine there, however, for some reason the internal webserver attempts to run (and the option to run on an external IIS is greyed out).
Anyone run into this problem with DNN Community edition? I've tried running as admin and setting permissions with no luck at all.
Any way to fix this?
Ok, the key is to delete the Database.mdf file completely.
Then create a new empty database of your choice in SQL Server (2008 or greater).
Create a new user account with db_owner access (as it must be able to create tables, etc).
Change the connection strings in the release.config and development.config to connect to the database.
DELETE the web.config file.
RENAME either config file to "web.config"
Set the default project to the web project in VS
set the default page to default.aspx
Run
I made the erroneous assumption that running the app would rename the config file for me (not sure why I assumed that).
SOLVED!
I am usimg VS 2010 Professional.And want to connect the TFS Testcase datasource without using MTM(Microsofot Test Manager).Is it Possible to do so.
[DataSource("Microsoft.VisualStudio.TestTools.DataSource.TestCase",
"http://TFS URL", "27211",
DataAccessMethod.Sequential), TestMethod]
public void CheckUserLogin()
{
PageObjects.BrowserInvoke();
PageObjects.TextBox(UIMapRepository.userName, TestContext.DataRow["UserName"].ToString());
PageObjects.TextBox(UIMapRepository.passWord, TestContext.DataRow["Password"].ToString());
PageObjects.ButtonClick(UIMapRepository.loginButton);
Assert.AreEqual("Logout", PageObjects.CheckElementExist(UIMapRepository.logoutButton));
PageObjects.ButtonClick(UIMapRepository.logoutButton);
PageObjects.CloseBrowser();
}
When I run this I get

I suspect you'll need to pass the authentication credentials along with the URL in the TFS connection string.

I have a SharePoint 2013 installation on a Window 8 machine.
I am trying to create a web application and it is taking forever. The creation process never stops. I checked in application event logs and found this error:
*Machine 'SHAREPOINT2013C (SharePoint - 43000(_LM_W3SVC_1458308317_ROOT))' failed ping validation and has been unavailable since '1/22/2013 3:56:48 AM'.*
Searched the web but could not find anything that works for me.
Can anyone suggest a way to resolve the issue? Thanks a lot in advance.
Below are my findings:
In order to recognize routing targets IIS has to be able to process SPPING HTTP method
To test run this code in Powershell:
$url = "http://your-Routing-Target-Server-Name"
$myReq = [System.Net.HttpWebRequest]::Create($url)
$myReq.Method = "SPPING";
$response = $myReq.GetResponse();
$response.StatusCode
If you get the following error message:
Exception calling "GetResponse" with "0" argument(s): "The remote server returned an error: (405) Method Not Allowed."
that means that web front end is not set up to process SPPING HTTP method
To resolve the issue run the following commands on each routing target server:
Import-Module WebAdministration
add-WebConfiguration /system.webserver/handlers "IIS:\" -value #{
name = "SPPINGVerbHandler"
verb = "SPPING"
path = "*"
modules = "ProtocolSupportModule"
requireAccess = "None"
}
This will add a handler for SPPING verb to IIS configuration.
Run the test script again to make sure this works.
So this has to do with the Request Management Service that runs on the WFE servers on SharePoint 2013. The Request Management Service is of no value since you only have one server. If you disable this service on your single server farm these messages will go away and your Web Application creation performance will greatly increase.

I recently faced this issue, I created new Web Application and it was showing a popup of "It shouldn't take long", then after some time it showed a Connection failure page. I browsed to the virtual directory folder for the new web application and found that the folder was totally empty.
Then what I did to solve this problem:
1. Open IIS
2. Go to Applicatin Pools
3. Select Central Admin application pool and right click and select "Advance Settings".
4. There was a property named "Shutdown Time Limit", it was set to "90" by default. I changed it to 400 and clicked OK.
It restarted the applicaition pool automatically. Then again I created new web application from central admin and it worked for me.
I've found that these events correlate to when the specified application pools are recycled (mine are at a specific time in the morning). It's unfortunate that they're logged in the event viewer and can't really clean it up.
I'm running into a problem with getting SSL to work in the Development Fabric. I'm running a clean install of Windows 8 Pro with Visual Studio 2012 Ultimate and the October 2012 Azure SDK for .NET. IIS8 is not installed, only IIS Express, which claims to support HTTPS so I'm hoping that's not the issue.
Running VS 12 as administrator, I've created a blank VS solution, added a new (.NET 4.5) cloud service with a new ASP.NET MVC 4 Internet web application project, and hit F5. Everything works fine. Then, when I add an SSL certificate to the web role and replace the HTTP endpoint (port 80) with an HTTPS endpoint (port 443, with the certificate), hitting F5 produces the following error message:
Windows Azure Tools for Microsoft Visual Studio
There was an error attaching the debugger to the role instance 'deployment18(32).WindowsAzureCloudService.Mvc4WebRole_IN_0' with Process Id: 4892'. Unable to attach. Access is denied.
Note, the last part ("Access is denied") comes in a few variations, a particularly pleasant one being "Catastrophic failure". :)
The only message in the VS Output window ('General' output) is:
Windows Azure Tools: Warning: Remapping private port 443 to 444 in role 'Mvc4WebRole' to avoid conflict during emulation.
The Compute Emulator UI is not much help; just before the instance disappears, this is the only console output that I get consistently (sometimes other messages appear, but sporadically every few runs; I'm not sure how to capture these):
[fabric] Role Instance: deployment18(33).WindowsAzureCloudService.Mvc4WebRole.0
[fabric] Role state Unknown
[fabric] Role state Suspended
[fabric] Role state Busy
[fabric] Role state Unhealthy
[fabric] Role state Stopped
The certificate was obtained from a CA and properly imported into the Local Machine/Personal/Certificates store as a .pfx with private key, extended properties, and marked as exportable, for what it's worth.
When I attempt to publish the service to Azure, I get one build (validation) warning about the database connection string (which I assume is irrelevant):
The connection string 'DefaultConnection' is using a local database '(LocalDb)\v11.0' in project 'Mvc4WebRole'. This connection string will not work when you run this application in Windows Azure. To access a different database, you should update the connection string in the web.config file.
Probably more important, the deployment actually fails with the following history in the Windows Azure Activity Log window:
9:00:25 AM - Warning: There are package validation warnings.
9:00:25 AM - Preparing deployment for WindowsAzureCloudService - 1/3/2013 8:59:55 AM with Subscription ID '<...>' using Service Management URL 'https://management.core.windows.net/'...
9:00:25 AM - Connecting...
9:00:26 AM - Object reference not set to an instance of an object.
9:00:26 AM - Deployment failed with a fatal error
Can someone help me troubleshoot this issue? I've rebooted a few times. ;)
Thanks in advance!
EDIT (Jan. 3, 4:44 PM): I have a few ideas that might help me make progress, but some are pretty drastic so any advice would be appreciated:
Is there a way to capture all the output from the Compute Emulator (Dev Fabric) to a log file so I can review it? (System.Diagnostic.Trace calls from my service won't help, since I don't even get as far as the RoleEntryPoint when using HTTPS!) I figured this out; see next edit.
That null pointer exception during the Azure deployment has me worried. Is it worthwhile to try reinstalling the Azure SDK, and if so, how should I go about doing a clean install of it?
Has anyone seen a problem of this sort disappear when switching to using full IIS for the emulator? (That seems unlikely since IIS vs. IIS Express should have no relevance to the Azure deployment.)
EDIT (Jan. 4, 10:15 AM): Bad news: I tried the suggestion to grant Read access to the certificates, but it didn't help in my case. Good news: I managed to capture one of those sporadic messages in the Compute Emulator UI before it shut down; it was a bit of info from some diagnostics. Not helpful in and of itself, but it revealed where the Development Fabric was storing its temporary files:
[Diagnostics] Information: C:\Users\Lars\AppData\Local\dftmp\Resources\0005155d-4592-40f4-812e-18793b26576c\directory\DiagnosticStore\Monitor
The GUID portion gets recreated for every deployment, and it is deleted when the deployment goes away (as it always does in my case). But in the parent directory ('dftmp'), there are a few helpful directories that I then monitored during a new deployment: DevFCLogs, DFAgentLogs, and IISConfiguratorLogs. I guess that answers the first question I had yesterday! :)
DFAgentLogs\DFAgent.log: (41KB) No useful information. A bunch of "Failure to read pipe" messages and failures to get the role/deployment instance ID, which I assume are just noise.
DevFCLogs\DevFabric--2013.01.04--<...>.log: (510 KB) No useful information. I skimmed the file and also searched for 'error', 'failure', 'not found', 'certificate', and 'Mvc4WebRole_IN_0'; none of those showed any hints of what was going on.
IISConfiguratorLogs\IISConfigurator.log: (6 KB) Now we're making progress!! :) Can someone tell me what this means? (In the meantime, I'm off ILSpy-hunting... fun fun...)

EDIT (Jan. 4, 11 AM): ILSpy wasn't much help; the exception is being thrown at an interop point (we knew that already) while trying to get the hash of a certificate in order to set up the binding (we knew that too). Does anyone know what COM object would need to be registered in order to get a certificate hash for a binding in Microsoft.Web.Administration? Or how I could intercept the interop call to find out? Bonus points if you can tell me why this is happening in the first place. :)
I've had similar problem on two computers. On both cases installing IIS solved the problem.
It seems to be enough to just install the IIS (via add/remove Windows components). You don't need to start using it. The installation changes something and after that my IIS Express started working again with HTTPS from Visual Studio.
There is a discussion on similar issue on MSDN Social:
http://social.msdn.microsoft.com/Forums/nl-NL/windowsazuredevelopment/thread/ad362016-16f6-459a-8022-9307aa5f910e
And the issue has been also raised on Microsoft connect:
https://connect.microsoft.com/VisualStudio/feedback/details/758533
In my case the error in the log files was:
IISConfigurator Information: 0 : [00007644:00000007, 2013.01.17
00:39:18.523] Exception:System.Runtime.InteropServices.COMException
(0x800401F3): Invalid class string (Exception from HRESULT: 0x800401F3
(CO_E_CLASSSTRING))
I found the log files from C:\Users\\AppData\Local\dftmp\IISConfiguratorLogs directory.
When running locally with a private key cert for SSL, you'll need to give the user the emulator app is running under access to the private key. Open mmc.exe and add the Certificates >> Local Computer Snap-In to view your certificate. Right Click on the certificate, then All Tasks >> Manage Private Keys - then add IUSR and Network Service with at least read access.
For deployment to azure, you'll need to upload the certificate to the Cloud Service and make sure the certificate is valid for the domain.

I am attempting to obtain a data feed from yahoo finance. I am doing this with the following code:
System.Net.WebRequest request = System.Net.WebRequest.Create(http://download.finance.yahoo.com/download/quotes.csv?format=sl&ext=.csv&symbols=^ftse,^ftmc,^ftas,^ftt1x,^dJA);
request.UseDefaultCredentials = true;
// set properties of the request
using (System.Net.WebResponse response = request.GetResponse())
{
using (System.IO.StreamReader reader = new System.IO.StreamReader(response.GetResponseStream()))
{
return reader.ReadToEnd();
}
}
I have placed this code into a console application and, using Console.WriteLine on the output I receive the information I require. I have used the 'Run as..' command to execute this using a specific domain account.
When I use this code from within a Page load I receive the following error message "No connection could be made because the target machine actively refused it 76.13.114.90:80".
This seems to suggest that the call is reaching yahoo (is this true?) and that there is something missing.
This would suggest there is an identity difference in the calls between the console application and application pool.
Environment is: Windows Server 2003, IIS 6.0, .net 4.0
"Target machine actively refused it" indicates that the TCP connection itself is not succeeding. This could be due to the fact that the Proxy settings when run under IIS are not the same as those that apply when you run in the console.
You can fix this by setting a WebProxy on your request, that points to the proxy server being used in the environment.
Yes, an active refusal is indication that the target machine is receiving the request and the information in the headers is either incorrect or insufficient to process the request. It is entirely possible that if you had to run this call using a "run as" command in console that the application pool's identity user does not have the appropriate permission or username. You can attempt to change the identity user to this specific domain account to see if that alleviates the problem, but you may have to isolate this particular function into its own application pool in order to protect the rest of the website from having this specification.
