open datareader associated with this connection error...

All of the sudden I'm getting the following error on my local web server (Win7 64bit, IIS 7.5).  I've uninstalled & reinstalled IIS locally and it didn't fix it.  IIS is set to start up automatically and I can see that the service has been successfully started.  Upon a fresh reboot if I go into IIS and click on start website I get the following error:

"The process cannot access the file because it is being used by another process.  (Exception from HRESULT:  0x80070020"

If I try to start debugging on my local website project I get the following error:

"Unable to start debugging on the web server.  The underlying connection was closed.  The connection was closed unexpectedly."

Any ideas on what I can try?  I've been doing research on the issue and Microsoft suggest making sure no other service is listening on the same ports.  I've verified that this isn't the issue.

Hi All,

i have a program in vb.net..i use the webrequest to post the data to another page (http://localpost/posReceived.aspx), and use the webResponse to get the back the response from the remote page.

When i run this program, it returned error "The remote server returned an error: (403) Forbidden.". I have no idea on this. Coz my aspx page and posReceived.aspx are placed in the same server and same directory. I supposed it should be worked without any security concerns.

Can anyone help me to solve it. Thanks a lot!

Here is the Code behind where i am calling "triggeroverlay" javascript function to display error to the user.

    public partial class _throw : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
          

        }

        protected void Button1_Click1(object sender, EventArgs e)
        {
         ClientScript.RegisterStartupScript(this.GetType(), "throwError", "<script>triggeroverlay();</script>");
        }
    }
}

I was reading this article about the same thing but didn't get it properly. Please help and give example where i am wrong and how to make it work.

Hello,

This error never happens before in my machine since 7 months of using it.

"There was an error while enumerating services on local machine:
Active Directory Services cannot find the web server. A possible cause for this is an incompatibility between versions of Internet Information Server (IIS) on the client and the server. Another possible cause is that IIS is not installed on the local machine, or the user identity under which you are running may not have permissions to view websites on this machine. To view websites on this machine, make sure that you run Visual Studio as administrator. On Windows Vista computers with IIS installed, make sure that IIS Metabase and IIS 6 configuration compatibility feature is enabled."

I'm trying to add back a webservice (localhost) after deletion. And suddenly I'm getting the above error.

The error's suggested tip is to install IIS but I did not install IIS since then in my machine because VS2010 built-in server do just fine. Should I install IIS?

I also found this helpful tips but nothing works.

    * Run Visual Studio with elevated administrator permissions
    * Be a member of the "Administrators" group on the local machine
    * Right-click the Visual Studio icon and select the "Run as administrator" option from the context menu


Any help is much appreciated. Thank You.
