Mike I'm developing an ASP.NET application and I've just moved over to Vista. I' developing using the local server. Under XP It connected to IIS quickly and my web application came up quickly. Since moving to Vista it takes 2-3 minutes to pull up my app on the local server.

Any ideas: bapo_10@hotmail.com

Robert,

Your best bet is to set up a Failed Request Tracing log with failure definition being a timeout of 1-2 minutes, and inspect it to see where the time is being spent.

Please use the instructions above to do this.

Thanks,

Mike

Hi I get an error when I try to run a classic asp website on vista: HTTP Error 500.0 - Internal Server Error Description: Calling GetProcAddress on ISAPI filter "C:\Windows\system32\inetsrv\asp.dll" failed Error Code: 0x8007007f Notification: Unknown Module: IIS Web Core Requested URL: http://scapatchi:80/ssri Physical Path: C:\inetpub\wwwroot\ssri\ssri Logon User: Not yet determined Logon Method: Not yet determined Failed Request Tracing Log Directory: C:\inetpub\logs\FailedReqLogFiles Handler: StaticFile Most likely causes: The ISAPI Filter has dependencies that are not available on the Web server. IIS received the request; however, an internal error occurred during the processing of the request. The root cause of this error depends on which module handles the request and what was happening in the worker process when this error occurred. IIS was not able to access the web.config file for the Web site or application. This can occur if the NTFS permissions are set incorrectly. IIS was not able to process configuration for the Web site or application. The authenticated user does not have permission to use this DLL. What you can try: Try running Reskit tool "depends" on the ISAPI DLL. Ensure that the NTFS permissions for the web.config file are correct and allow access to the Web server's machine account. Check the event logs to see if any additional information was logged. Verify the permissions for the DLL. Create a tracing rule to track failed requests for this HTTP status code. For more information about creating a tracing rule for failed requests, click here. What can I do?

Mike Volodarsky — Tue, 28 Aug 2007 13:03:10 GMT

Dmitrios,

You have added the ASP.dll ISAPI extension as an ISAPI filter, which is incorrect. You shouldnt need to manually create this mapping - simply install ASP from the Turn Windows features On/Off UI, and it will automatically create the handler mapping.

Thanks,

Mike

Matt McGinty — Thu, 18 Oct 2007 15:30:06 GMT

Mike, I'm hoping you can help me. I've installed ServletExec 6.0b1 into my IIS 7 (on Win 2008 RC0). It works fine and I am able to request simple Servlets and JSPs. The issue I have is when I request a JSP which returns a 500 status code (on purpose) with a custom response body. In this case the custom response body is configured inside ServletExec (the Servlet/JSP engine which is "hooked into" IIS as an ISAPI Filter). I want to see that custom response body. But instead IIS 7 is being fancy and "stomping on" my custom response body. IIS 7 is returning a preconfigured 500 response body. I removed the error page mapping for the 500 status code (did this in the IIS Manager) for my IIS website. But while doing that *did* change the behavior slightly, it did not fix the issue. Now when I request my JSP, IIS 7 returns this response body: The page cannot be displayed because an internal server error has occurred. No... I know and expect that an internal server error occured (remember that my JSP sets the status code to 500 on purpose). So I actually want an error to "occur". But I want to see the response body that my JSP built... not the response body that IIS 7 "inserts". I've also removed the IIS 7 error page mapping for the 500 status code at the "global" level of IIS (not just the level of my specific IIS website) but that did not have any effect. Can you help me? Thanks. -Matt McGinty

Hi Mike, We are having some issues with our production enviornment. It seems that the web servers stop responding when the worker processes are recycled. The only way we can get it to respond again is to reset IIS. We've currently set the worker process idle time down to 0, and the recycling to happen every hour, and sure enough, every hour we have to reset IIS. We've got an IIS module to do some basic URL rewriting, and on load test it performed fine. Additionally, we didn't see anything like this during our load tests, but it started happening as soon as we went live. We're also not getting any exceptions being raised, and the CPUs look relatively idle (< 5% utilisation) and memory usage is OK, too (~ 60%) when the servers stop serving requests. There doesn't seem to be anything significant in the event log either. What we do get in the event log is a message stating tha the worker process had requested a recycle as the wp reached its allowed processing time limit, and this is followed by a message saying that the wp exceeded time limits during shut down.

re: Troubleshoot IIS7 errors like a pro

Mike Volodarsky — Sat, 08 Dec 2007 18:00:22 GMT

Hi Zack,

You'll need to look at your problems one at a time. Typically when you get a 404.3, it means that you havent installed the correct handler mapping for your resource type, and therefore IIS refuses to serve your (script) file as a static file. When you install ASP.NET, or ASP from Windows Setup, they create the handler mappings by default. If you have other ISAPI extensions or modules, you need to create the handler mappings manually.

Run:

> %windir%\system32\inetsrv\appcmd list config -section:handlers

To see if it contains handler mappings for your desired extensions. If it doesnt, thats your problem.

For a more detailed investigation, please post the detailed error and the result of the above command on the IIS.NET forums and we'll help you.

Thanks,

Mike

re: Troubleshoot IIS7 errors like a pro

Mike Volodarsky — Sat, 08 Dec 2007 18:09:35 GMT

Hi Kyri,

Is there anything in the "System" Event Log that indicates that a worker process failed to start, or failed, causing WAS to disable your application pool?

Re: wp exceeded time limits during shut down

Something in your worker process may be taking a long time to shut down, so WAS ends up killing it. it can be a request that has hung. You can check the currently executing requests to see if any requests have been executing for a really long time for a clue.

Additionally, you can try attaching a debugger to the process after it is scheduled to go away and dump the thread stacks to see what threads are doing.

Another thing you may want to try is extend the shutdownTimeLimit to see if a little bit of additional time will help the process go away. You can set it as follows for any apppool:

> %windir%\system32\inetsrv\appcmd set apppool "<YourAppPoolName>" -processModel.shutdownTimeLimit:<TIMESPAN>

Also, be sure that your apppool is set to allow overlapping recycles so that a new worker process can be started to handle requests while the other one is shutting down:

> %windir%\system32\inetsrv\appcmd set apppool "<YourAppPoolName>" -recycling.disallowOverlappingRotation:false

Thanks,

Mike

Umm, my computer said 404.4 error when i tried to go to localhost, and it said something about a handler, how do i fix that?

re: Troubleshoot IIS7 errors like a pro

Mike Volodarsky — Sun, 30 Dec 2007 04:06:03 GMT

Qebafhzn,

This error means IIS couldnt find a handler for your request extension and verb. Check that you have the extension and verb mapped to a handler in InetMgr, by selecting your application in the tree view and clicking the "handler mappings" feature. There should be an entry for your extension mapping it to the appropriate handler, or there should be a * mapping that will serve all other requests as static files. The fact that you are not getting a 404.3 error means that you've either removed the * mapping for the static file handler, or your handler mapping is preconditioned incorrectly preventing it from being used in your application.

If this doesnt help, post to forums.iis.net and we'll walk you though it.

Thanks,

Mike

I've looked all over for and I can't figure it out. My css files seem to be blocked by IIS7. My site displays them when I use the ASP.NET Development server, but when I browse to the applicaiton, the styles are not applied. Is there a setting somewhere in IIS7 that is preventing the css files from being downloaded by anonymous users? My css files are located in /App_Themes/Default/Default.css I've given permission to NetworkService to view this area. I could go on with all the trouble shooting steps I took, but I'm hoping this may be a simple issue. Thanks.

re: Troubleshoot IIS7 errors like a pro

Mike Volodarsky — Sat, 02 Feb 2008 17:47:58 GMT

Hi Victor,

You do not have to "click in all possible windows". IIS 7.0 provides lots of diagnostical information, but it also must strike a balance between accessibility of this information, security, and performance in generating and storing it.

I generally dont respond to nonsensical blanket statements like "Microsoft is simply not programmer friendly". If you have a question about troubleshooting IIS 7.0, or a specific suggestion for what we can do better, do post back.

Thanks,

Mike

re: Troubleshoot IIS7 errors like a pro

Mike Volodarsky — Sat, 02 Feb 2008 17:51:07 GMT

Hi Jason,

The best bet is to request one of the .css files directly in the browser, or using a tool like WFETCH, and see what happens. You will need to turn on the detailed errors as I describe in this post, and possibly obtain a failed request trace log.

If I were to guess, you are missing the MIME Type entry for .css which results in the static file handler rejecting the request with 404.3.

If you still need help after you follow these steps, please post on forums.iis.net and we'll help you further.

Thanks,

Mike

hi Mike,

I could swear that I read pre-release information that said IIS 7.0 would allow a custom error response (page) similar to the custom.html in IIS 6.0.

While I know we need to find the source of this in our application, this error is directly impacting a customer so we are trying to "mask" it while we find the issue.

Is this available and if so, could you be so kind as to point me int he direction of MSDN or other appropriate documentation.

Thank you kindly for your time and assistance.

-Stephen

re: Troubleshoot IIS7 errors like a pro

Mike Volodarsky — Tue, 26 Feb 2008 04:34:17 GMT

Hi Steph,

While I definitely recommend that you get to the bottom of the issue, you can do the following:

1) configure a custom redirect for all errors in the application or that specific error

2) configure a Failed Request Tracing rule to capture the log of any requests that result in this error (using a statuscode/substatuscode based failure condition), so you can analyze them later.

You can configure both from IIS Manager.

Thanks,

Mike

I have the same problem (I think). My 2K8's x64 IIS7 is running normally - all ASP pages can be seen and run. HOWEVER - if I want to use any classic ASP COM/DLL objects, I get this error: Microsoft VBScript runtime error '800a01ad' ActiveX component can't create object I haven't changed anything to these pages since I ran my 2K3 box. I have: - successfully registered the same components. - made sure that IIS users / network service has access to the files - checked with process Sysinternals Process Monitor that no files can't be accessed (I don't see any errors) - checked DLLs with "dependency walker", gpsvc.dll copied to C:\Windows\system32\ All...to no avail. So why Have the IIS team made life difficult for the people who spent $ in order to upgrade from 2K3r2?

re: Troubleshoot IIS7 errors like a pro

Mike Volodarsky — Fri, 04 Apr 2008 16:47:56 GMT

Klaus,

If I was to guess, this is most likely because you are running the app in an application pool using syswow64 (emulated 32 bit mode) and your COM DLL accesses are being redirected to the syswow64 directory.

This would happen if you copied your COM object DLLs into the %windir%\system32\ directory.

For more info on what other issues it could be, see http://support.microsoft.com/kb/194801.

Mike

Hi Paul,

Please get the detailed error message and post back or to forums.iis.net to get more help (see this post for instructions on getting the detailed error).

Your issue most likely has to do with some configuration conflict between the base configuration on your own server, and the new configuration you added (for example, specifying web.config configuration for a section that is locked at the server level). Or, you may have differences in installed features or the application layout or permissions.

In any case, without knowing the detailed error, there is no intelligent way to move forward.

I followed your advice above just after I had posted the problem I was having and the advice you gave helped me solve the issue.

I'm not quite sure why the files worked on one server but not the other, it was perhaps as you say a difference in configuration between the two. I

ts turns out there was a php parsing error in a line of code which my server didn't seem to like too much and when I removed it (wasn't really required anyway) my page displayed again.

Mike, I have installed IIS 7 on a Vista machine and get a 404 error (The requested resource is not found) when I try to run a simple ASPX file. In IIS, if I click on the "Browse *:89 (http)" option on the right of the virtual directory page, I get the same error. ASP was checked during the IIS installation. Symantec Endpoint Protection is running on the machine.

Hi sampath,

You most likely have a permission issue. Make sure that IUSR has access to your database, if you are using Windows Authentication, or use sa authentication with credentials in the querystring.

For additional troubleshooting, post on forums.iis.net.

Thanks,

Mike

re: Troubleshoot IIS7 errors like a pro

John Hughes — Fri, 22 May 2009 06:59:52 GMT

Here's one that's not listed here.

IIS stopped responding to requests to localhost, 127.0.0.1, and [::1]. These used to work, but recently they stopped working. Using the local pc's actual ip address works, such as 192.168.0.123.

In firefox I get: Firefox can't establish a connection to the server at localhost.

In IE8 I get: Internet Explorer cannot display the webpage. -- And clicking the Diagnose Connection Problems button results in "localhost" is not set up to establish a connection on port "World Wide Web service (HTTP)" with this computer.

I have restarted the pc, done an iisreset, ensured that the web site binding is set to *:80. I also temporarily tried adding 127.0.0.1:80 as a binding, but that had no effect.

My hosts file looks like:

127.0.0.1 localhost

::1 localhost

When I run SysInternals tcpview command line I see:

[TCP] System

PID: -1

State: LISTENING

Local: 192.168.1.123:80

Remote: 0.0.0.0:0

Shouldn't that be 0.0.0.0:80?

I CAN successfully ping localhost AND I have an application called SqueezeCenter installed that has a built in web server on port 9000, and it works fine with localhost, 127.0.0.1, and [::1] requests.

As a side note, the same issue applies to WCF in .NET 3.x regardless of the listening port #. It no longer responds to localhost requests.

This started a couple weeks ago and I'm not sure what has changed to cause this.

Any ideas?

Thanks,

Johnny

I solved the problem I posted earlier, but it might be helpful to others. I ran across the following command line that apparently lists all the ip addresses that IIS is listening on (but I'm not sure how this differs from the IIS web site bindings): netsh http show iplisten This showed one ip address, which was my machine's ip address.... and I have no idea how it got set. Once I removed the ip address so the list was empty (which is what I have on another vista machine for comparison), localhost started working again. Johnny

I am getting error 404.4. It says "The resource you are looking for does not have a handler associated with it." In the "things you can try, it states, "If the file extension does not have a handler associated with it, add a handler mapping for the extension." However, it doesn't explain how to do this. Config of System: OS: Windows Vista Home Edition. Browser: IE 7.0 The system has Visual Studio 2008 installed on it. So the application runs on local host. But it does not have an IIS server installed. This error cropped up after I tried to run Spike Proxy (Web Application Security Testing tool) on my system, for which I had to change my browser settings. But after using it I changed the settings back to wht they were. But I am still getting the error. Please help me with this…..

Ok, adding the solution to my error so that others dont have to lose the 5 hours I did :( . I have vista business and I was adding IIS7 so I can start to learn to develop ASP.NET stuff. My book (and some other sites) said to add ".NET extensibility, ASP.NET, ISAPI Extensions and ISAPI Filters" in the turn on/off features window. I did this and when i tried to hit "http://localhost/" all i got was a blank screen. wfetch.exe (1.4) was telling me HTTP 200 but 0 bytes transferred. The solution: I had to goto the turn on/off windows features again and turn on both of the two options "Internet Information Services" --> "World Wide Web Service" --> "Common HTTP Features" --> "HTTP Errors" and "Static Content" . It was probably the static content option that made it work, but I turned them both on, then tried and it worked for me. (Getting the default IIS7 welcome in many languages page). Now to see if I can learn ASP.NET :)

We are experiencing a problem in uploading files to web server using the WEBCLIENT interface in Windopws 2008. Our application code was working perfectly when our IIS server was running in Windows 2003 but when we ported it to Windows 2008, it started throwing "(404) Not Found" exception. This happens on the "GetResponse()" method of webrequest Folowing is the code we are using: // The WebRequest oWebrequest = (HttpWebRequest)WebRequest.Create(oUploadURL); oWebrequest.ContentType = "multipart/form-data; boundary=" + sBoundary; oWebrequest.Method = "PUT"; // This is important, otherwise the whole file will be read to memory anyway... oWebrequest.AllowWriteStreamBuffering = false; // Get a FileStream and set the final properties of the WebRequest oFileStream = File.OpenRead(vsLocalPath); iLength = oFileStream.Length; oWebrequest.ContentLength = iLength; oWebrequest.KeepAlive = false; oWebrequest.Timeout = 4 * 60 * 60 * 1000; //4 hours; //20 * 60 * 1000 oRequestStream = oWebrequest.GetRequestStream(); // Stream the file contents in small pieces (4096 bytes, max). [changed to 65536, 262144] bFile = new Byte[iChunkSize]; //Upload the file while ((iBytesRead = oFileStream.Read(bFile, 0, bFile.Length)) != 0) { oRequestStream.Write(bFile, 0, iBytesRead); iProcessedSoFar += iBytesRead; } //Get response of transfer oWResponse = oWebrequest.GetResponse(); oResponseStream = oWResponse.GetResponseStream(); oResponseReader = new StreamReader(oResponseStream); rsErr = oResponseReader.ReadToEnd();

Server Error in Application "Default Web Site" -------------------------------------------------------------------------------- HTTP Error 500.0 - Internal Server Error Description: The page cannot be displayed because an internal server error has occurred. Error Code: 0x80070003 Notification: ExecuteRequestHandler Module: IsapiModule Requested URL: http://localhost:80/ Physical Path: C:\inetpub\wwwroot Logon User: Anonymous Logon Method: Anonymous Handler: AboMapperCustom-24377840 Most likely causes: IIS received the request; however, an internal error occurred during the processing of the request. The root cause of this error depends on which module handles the request and what was happening in the worker process when this error occurred. IIS was not able to access the web.config file for the Web site or application. This can occur if the NTFS permissions are set incorrectly. IIS was not able to process configuration for the Web site or application. The authenticated user does not have permission to use this DLL. The request is mapped to a managed handler but the .NET Extensibility Feature is not installed. What you can try: Ensure that the NTFS permissions for the web.config file are correct and allow access to the Web server's machine account. Check the event logs to see if any additional information was logged. Verify the permissions for the DLL. Install the .NET Extensibility feature if the request is mapped to a managed handler. Create a tracing rule to track failed requests for this HTTP status code. For more information about creating a tracing rule for failed requests, click here. More Information... This error means that there was a problem while processing the request. The request was received by the Web server, but during processing a fatal error occurred, causing the 500 error.

All errors, even 404 errors, display just this text: "The page cannot be displayed because an internal server error has occurred." Do you have any advice on troubleshooting this error?
