We have a .NET web application which runs perfectly when using http and https. The point is that after uploading a large file (no so large, more than 4 MB is enough) through https, the IIS hangs (in fact, is the tab from which we uploaded the file). We have already configured all the IIS properties related to the content length and maximum size of the files. We have been reading other threads related to this, but we have not got the solution yet (https://forums.iis.net/t/1197751.aspx?IIS+7+5+CGI+SSL+Problems+with+upload+limit+30MB+cap+). Any help will be very appreciated. Thank you very much.

Good afternoon!

We have a network share we're using for file storage that is accessed through a virtual directory for download. When a user downloads a file, we're seeing some files get corrupted, XLXS and ZIP files example, though TXT files seem down load just fine.

Here's a screen capture comparing the binary data of two zip files. Left is the file share, the right is the local, downloaded copy. You can see where the data is changing starting with the second line.

The original file, on the file share, is 5,521 bytes. The corrupted file is 9,601 bytes.

I've confirmed it's not the upload process

I've confirmed it's not storage of the files.

I've confirmed it's not our HTTP monitoring module.

I've confirmed it's not response compression gone horribly wrong.

Any thoughts on what could be causing this or to troubleshoot it?

Hi,

I have created a local ceritficate and bing it to my local app, in the iis manager if i click browse the site from there i can access the site and see the certificate and secure.

but if i access that local server from my laptop which is on the same intranet, its showing invalid certificate.

Hello,

I am new to IIS and I am trying to debug a web-based application.  IIS doesn't appear to be doing any logging of its web server.  I was initially trying to find the log file path since there's nothing in the default place.  I want to turn on and configure logging.  All the information I have found says there is supposed to be a Logging icon in the IIS Manger where it can be configured, but I don't see it, except for FTP.

This is IIS on Windows Server 2012.

What am I missing?

IIS application pool stopped automatically  after OS update. Following are the the logs and dmp info. Can anyone help me? I dont know how to upload the .dmp file captured by debug tool.

A process serving application pool 'X' suffered a fatal communication error with the Windows Process Activation Service. The process id was '6032'. The data field contains the error number.

Application pool 'X' is being automatically disabled due to a series of failures in the process(es) serving that application pool.

Hello IIS support team,

I am touching on a known issue regarding "." (dot) characters in the URL which causes a 404, more specifically with the .well-known for google deep links.

The main issue is that when I create a virtual folder called ".well-known" (on the root or any other location of the site) and link it to the physical path I am not able to access the virtual folder path via the URL.

Please take note of the following information below:

1. 1. I am able to access the physical "well-known" folder directly in the URL with folder browsing enabled.
2. 2. I am able to access ANY virtual directoryWITHOUT the "." (dot) in the URL.
3. 3. I have tested with the following modifications to the web.config:
5. <modules runAllManagedModulesForAllRequests="true" />
7. <validation validateIntegratedModeConfiguration="false" />

<add name="ApiURIs-ISAPI-Integrated-4.0"
path="/*"
verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS"
type="System.Web.Handlers.TransferRequestHandler"
preCondition="integratedMode,runtimeVersionv4.0" />
</handlers>

1. <requestFiltering allowDoubleEscaping="true" />

<httpRuntime relaxedUrlToFileSystemMapping="true" />

4. I have attempted to convert the folder to an application and copy the URL scan ini into the "app" but it does not seem to work either.

5. The only working solution I have found is to modify the "AllowDotInPath=0" to "AllowDotInPath=1" in the URLscan file, this however is considered as a security risk and will not be allowed on the particular site we are hosting.

If you could please advise on a solution or work around that possibly does not involve hosting another site on the server.

Regards,

David

Hi,

I am faced with the following troubling issue and I am running out of options what to try out in order to get a website up and running again. (The following is happening on Windows Server 2012 R2 with IIS 8.5.9600.16384 on two different servers, one is a productive server and the second one is a staging one, so they are configured very much the same, on normal test servers the application is running without issues)

An application hosted in the IIS that used to work is not starting up and there is nothing in the logs or the windows event log that hints at the issue. This happened after stopping a website, replacing .dll files of an application and then starting the website again. However, also when rolling back (copying the old .dlls that used to work), the application is not starting. Furthermore, after restarting the whole IIS, the second application on the same IIS (that had no changes) could also not start any more (there are no other websites on this IIS). Running out of options, I tried analysing a memory dump taken from w3wp.exe (see stack trace below), which hints at some issue loading the .dll files, as a thread is hanging there no matter how long you wait. In the memory for LoadAllAssembliesFromAppDomainBinDirectory it can be seen that it gets the correct folder, as the System.IO.FileInfo[] Array is filled with the FileInfo for the correct .dll files. This looked like there might be some file access issue, but the file and folder settings seemed fine. Tried to make a new pool and giving rights to the new application pool identity also did not change anything. Using the "nuclear" option and giving full control to "Everyone" also did not result in the website starting, so it seems it is not related to file access rights. Adding a dummy application to the server also resulted in that dummy application not starting. The application therefore does not seem to be the issue, as the same version was already running on the same server before, and is running on other servers. It was also tried to uninstall some of the latest windows updates, but that has not yet resulted in the websites starting again.

I hope that you have additional ideas what can cause this issue.

Kind regards

I have a site on IIS 10 that uses server side include directives.  It works great except one thing.

<!--#include file="hours.html"-->

If i go to any url of my page, such http://www.site.com/index.html  -  this works.

But if i go to www.site.com/index.html/foo   - this should be a broken link but instead it returns the index.html with all of the relative paths wrong (css and js broken). It should be a 404 correct?   I think i want it to be a 404.   Problem is google custom search is finding a bunch of these  index.html/foo type links.

The problem goes away if i disable server side include.  Any assistance would be appreciated.

Hey, I am new to Windows Servers and I experienced a very frustrating error.

I installed Windows Server 2019 and IIS on my laptop to see how this works. The system is fresh and until that point, I only installed Windows Server and after that IIS by following the non-GUI-guide here:

https://www.rootusers.com/how-to-install-iis-in-windows-server-2019/

After the installation, I wanted to see results, but IE only brings up 503.

I looked it up and the most common problem is a stopped Application Pool, so I checked that and it's running.

I checked the Event Log, but it's empty. After that, I checked the http-errorlog at windows\system32\LogFiles\HTTPERR and it shows nearly nothing.

I did a netstat and it says that something is listening on port 80. I looked up the pid in the task manager and it says "system". I don't know what to do next.

I loaded up the screenshots here:

Hello,

I have configured 3 local sites in IIS 8.5 running on Windows Server 2012 R2.

I'm using msdeploy.exe  for local deployment with below configuration.

cd C:\Program Files\IIS\Microsoft Web Deploy V3\
msdeploy.exe -verb:sync -source:package="xxx.zip" -dest:"auto" -setParam:name="IIS Web Application Name",value="reverseproxy" -allowUntrusted=true -verbose

All these sites were configured identically and all of them have the rewrite2 module installed and IIS_IUSRS added and configured in security permissions of each backend folder.

2 out of 3 sites run without any problems and I do receive response from API POST commands.

I have an issue with the third site that does not run and I don't see any obvious reason of this issue.
HTTP ERROR 500 received when I access using local web browser and when I query a POST requests to API.

Looking at inetpub log folder I do see the following errors written to the log file "500 19 13"

There are no related error entries in windows Event viewer

Is there any additional place  to look for IIS logs \ errors ? 

Please advise further troubleshooting steps.

the site works fine if I go directly to the page https://123.abc.com/apps/index1.php, but if try using https://123.abc.com i get

There is a problem with the resource you are looking for, and it cannot be displayed. or 500 19 183 31 errors in the logs.

Permission NTFS permissions look correct.

We have two servers:

Server I: 10.0.1.3 (Debian 10 / Apache 2.4)

fqdn: music.domain.com (LAN access only)

Server II: 10.0.1.5 (Windows Server 2012 R2 / IIS 8)

Fqdn: gateway.domain.com (LAN and WAN access)

Both servers have the wildcard SSL certificate from DigiCert installed and properly configured for ssl connection over https (*.domain.com)

On server I we have a media application (Airsonic – json based )

https://music.domain.com/airsonic

From the LAN everything works flawlessly, all browsers can load Images, Frames, Scripts, Audio/Video files…

On Server II we have IIS working as a reverse proxy rule to access the Server I as follow:

<rule name="Airsonic" enabled="true" stopProcessing="true"><match url="airsonic(.*)" /><conditions logicalGrouping="MatchAll" trackAllCaptures="false" /><action type="Rewrite" url="https://music.domain.com/{R:0}" /></rule>

When we try to access the https://gateway.mydomain.com/airsonic from any browser then we have the following issues:

• Failed to load resource: net::ERR_FAILED
• Uncaught (in promise) DOMException: Failed to load because no supported source was found.
• Uncaught (in promise) DOMException: The element has no supported sources.
• Cross-Origin Read Blocking (CORB) blocked cross-origin response https://music.domain.com/airsonic/login with MIME type text/html

Although we can access the application from the gateway, some frames would not load correctly, and audio and video files won't play at all!

this is our web.conf file

We can only assume it's something to do with the configuration of IIS (reverse proxy rule), since if we bypass the gateway we have no issues playing audio/video... Our ultimate goal is to access the Airsonic Application from the WAN without connecting directly to the server I as we already configured the firewall to forward the proper ports to Server II!

How to establish trust between the content sent to and requested from between Server I and Server II that won’t fail with CORS/CORB and remain secure?

PS: We are NOT savvy in web.conf, so please give an example of how to make the rule rather than just mentioning what is supposed to be done...

Thank you in advance for helping with this matter,

I'm working on a C# project which runs fine from my development workstation VS2019. The application makes a REST API call to a server which runs a procedure and returns a response. Everything works fine from my workstation. But when I post the project to IIS8 server and run it I get an error Could not create SSL/TLS channel.

The error occurs when I call WebResponse webResponse = request.GetResponse();

I've updated the server to .NET 8.0 . Any help is much appreciated.

        //Production Server
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://api.myibservices.com/v1/authenticate");
        string authInfo = "XXXXXXXXX:XXXXXXXXX";

        request.ContentType = "application/json";
        request.Method = "GET";                               
        authInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo));
        request.Headers["Authorization"] = "Basic " + authInfo;

        WebResponse webResponse = request.GetResponse();

        using (StreamReader reader = new StreamReader(webResponse.GetResponseStream()))
        {
            response = reader.ReadToEnd();
        }

In addition the server uses Tls12 which is part of my code at the beginning of the method: ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

I receive an error message when I try to connect to Outlook and PowerBI. The error is

aadsts5000811 unable to verify token signature

The reason I feel this is an IIS issue the fiddler requests start off by a tunnel to login.microsoft.com, which then hits the urlhttps://analysis.windows.net/powerbi/api with a login_hint, and a redirect_uri a well as other webform values.

What occurs next is the adfs/ls?login_hint passed an X509 certificate back to login.microsoftonline.com and fails with this response.

We're signing PDF documents with a certificate on various websites, and after upgrading Server 2008 R2 > Server 2012 > Server 2016, all of the OLD AppPools have the proper permissions, and those websites create properly-signed PDFs just like they did before the upgrade.

But any NEW IIS Application Pools we create do NOT receive permissions on the MachineKey file in C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys\ and document-signing fails.

Running Process Monitor shows the following:

* DocumentSigningSoftware.exe succeeds when accessing C:\Users\AppPoolUser\AppData\Roaming\Microsoft\Crypto\RSA\

* DocumentSigningSoftware.exe and LSASS.exe get Access Denied errors on CreateFile in C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys\

Questions:

1) For new App Pools, is the solution simply to use cacls.exe to add Full permissions on the Machine Key file in the \RSA\MachineKeys\ folder?

2) How can I get Windows Server to add the permissions when new App Pools are created?

3) Should I be concerned about any other problems that may arise due to the in-place upgrade to Server 2016?

Thanks.

I recently had to publish an API, I did it in an application within a website, as I did for all my previous web services.

There were a DNS set up so the API should be accessed this way:

http://MyServices/MyAPI/...

But we couldn´t make it work... we get an unhandled exception when the API was invoked and not much info.
All other WCF services published there where working with no probs (http://MyServices/Service1/...http://MyServices/Service2/... etc)

When trying the services with Postman and everything seems fine, when accesing from the website (hosted in its own websitehttp://MyWebsite/) we got the unhandled exception.

Obviously, in the development server everything was working fine, just in the Staging Server (copy of Production one) was failing. But there were no differences in permissions that we could see.

After 2 days trying almost everything, I did republish it in a brand new website (for my test I used:http://MyServer:8012/ (I was testing too many things to create a DNS for each test) and it start working correctly.

My question is: Why? I solve this issue today, but now Im trying to find out why that happened.

If it helps, I was using IIS 8.5, the framework used was 4.5.2

I am using IIS10 with tomcat server via isapi.

However, after restarting IIS, the webpage throws 500 errors.

After reconnecting, the connection is established normally.

The problem above occurs after some time has elapsed.

I'm attaching a log to fix this.

I have IIS Shared client configuration with certificate rules defined in IISClientCertificateMappingAuthentication/manytoOneMappings at website web.config level.

Suddenly I found I was getting HTTP 401.1 error when trying to access the web-service. Looking at the certificate rules in IIS, I found the password field is empty for all rules.

I removed the IIS Shared Configuration. Now when I try to add a certificate rule I get error "the value does not fall within the expected range". 

I have tried reinstalling IIS feature from Windows Server 2012 but it hasn't helped.

Any help is highly appreciated!

Hi experts,

I am trying to create my FTP Server, I am following this tutorial: https://www.windowscentral.com/how-set-ftp-server-windows-10

When installing the windows features, I am getting the 0x800F0922 error towards the end of the installation.

I have done hours of searching but keep hitting a brick wall.

I have tried to install through cmd admin, dism via cmd admin, restart the computer as it suggests itself, check the regedit to delete one of the records that might cause this issue, but the record doesn't even exist for me to delete.

I have also done the check health and restore image commands and both say there are no problems found.

Hope someone can help!
