We are using IIS 8.5 with server 2012 and .net 4.5. Lot of requests of clients are going to request acquire state in work process, these are not killing after session out. Presently we are recyling on regular basis for get rid of. What can be the issue ??? 

Hello forum.   Looking for some troubleshooting assistance on a problem affecting our servers that run an FTP site secured with an SSL cert.

We have about 150 servers running their own FTP site.   FTP is set to Require SSL connections and its configured to use an SSL certificate from our internal CA.   Everything looks good with the cert - no errors, has private key, and the issuers are good (subordinate and root).   However, thing to note, each cert is almost exactly half way thru its life - issued this day or one prior in June 2016, and the expiry is this day or one more in June 2018.  

These 150 servers have been in place for about a year.   Over the last week, multiple servers' FTP sites have dropped the SSL cert from the site config - just reverts to 'Not Selected' for no reason.   It's a day or two plus a year from the time the server was deployed and configured (we have the deployment schedule on our wiki).   It's a simple fix, reselect the cert from the drop down and bobs your uncle.   Problem is FTP connections don't work from the time the cert drops (1:40/2:00am) until we fix it.

I got nothing in the my App or System logs about the time it dies.   The servers have not been rebooted in about a month (uptime is about 30 days) and no patches or recent changes are known.

Without something to go on I'm stuck seeing sites die overnight and support teams getting paged.   Can anyone offer some troubleshooting tips for me ?

Thanks,

JC

Hi,

Our web site is called by SystemPay  (a payment website). And IIS is on timeout with the following call  :

System.Web.Hosting.IIS7WorkerRequest:ReadEntityCoreSync  (35s)

We don't understand why it happens. (we're using Appdynamics to see all cals)

Hi

We have a VM server Windows 2016 in Azure which has IIS 10 installed. All is going great except for CPU throttling. It just does not work on this Windows 2016 and/or IIS.

Settings for the app pool are:

- Limit: 90
- Limit action: Throttle
- Limit Interval: 5

In Windows 2012R2 it all worked perfectly.

I have looked at Windows System Resource Manager (WSRM) but thats not supported anymore. 

It is safe to say that IIS 10 is useless without this feature.

I hope you can help !

Hello, I would like to develop a classic ASP script that would run automatically when an http 500 error occurs. This script will allow me to send by email the url of the page in error, as well as the detailed error. Could someone help me?

I specify that I am on the latest version of IIS (windows server 2016)

I have a Windows Server 2012 R2 Standard running on AWS using IIS 6.2 (Build 9200).

Several times the website stops responding, looking in the event log I found this, not sure if this is the problem but look likely.  Restarting IIS fixes the problem but I have to log into do it.  And of course the site is down the whole time.

Suggestions?  I am running an MVC 5 application.

"A worker process '4360' serving application pool '.NET v4.5' failed to stop a listener channel for protocol 'http' in the allotted time.  The data field contains the error number."

Hello, a while ago I created a dll in c++ which uses the IHttpHandler Interface. I have been able to register and verify this module does what it is supposed to do on more than 8 virtual machines(IIS >> modules >> configure native modules >> register). I am using hyperv and those machines were created from a sysprepped image. I use the same dll file on all machines. The issue I am having is that it is not working properly on just one of those machines. As soon as I register the x64 module, when someone visits a websites, the application pool of the website goes down with message in the application log: "The Module DLL 'C:\the-name-of-the-dll.dll' could not be loaded due to a configuration problem. The current configuration only supports loading images built for a AMD64 processor architecture.". None of the application pools have "enable 32-bit applications" set to true. The OS is windows 2012R2 x64. I have built two versions of the dll - x32 and x64. I have no problems registering the x32 bit one. If I register the x64 bit dll and set "enable 32-bit applications" to true for an application pool, it works. I have also verified with process explorer that the w3wp processes run in x64 bit.

<add name="the-name-of-the-dll" image="C:\the-name-of-the-dll.dll" preCondition="bitness64" />

Below I am pasting the output from dumpbin /headers for both the x32 and x64 version of the dll. I have tried restarting the VM, restarting IIS, removing and readding the DLL, but nothing seems to work.

I am running serveral localhost sites on IIS 8. Recently they have become unreachable by any domain computers and IIS8 itself when using the bound IP (192.168.1.x:xx). When testing with Windows firewall off and telnetting to a bound IP I am still unable to reach it. However, when I set the binding to "unassigned" with a port, I can reach it just fine. What's happening?

Thanks!

Hi.

I have IIS 8.5. I am trying to configure my application for 2 variants of authentication - SSO, and CAC (smart-cards).

Application is hosted on 4 tomcats (2 for SSO and 2 for CAC), each is configured for their authentication method.
Also I've configured 2 ISAPi redirectors: SSO and CAC.
In IIS I've created 2 Virtual Dirs: jakartaSSO and jakartaCAC, 2 ISAPI filters for each and enabled handler mappings for execute.
Also configured parameters for each jakarta (SSL, Authentication, Bindings)

But the problem is that, when I’m checking jk status I see only 1 worker which balances 2 tomcats. And where is the other worker?
Also jk status is working https://<hostname>/jkstatus.
How to configure it to view jk status for each virtual dir like: https://<hostname>/jakartaSSO/jkstatus ?

Thanks!

Best regards,

Hi, everyone!  So here's what I'm running into.  I've got 3 Server 2008 R2 VMs.  One IIS 7.5, one Tomcat 7 and one SQL Server 2008 R2 SP3 (with TLS fix added).  The website works great with TLS 1.0 enabled and communicates through Tomcat to the SQL Server. It's setup for simulated CAC authentication by using user certificates.  However, when I disable TLS 1.0 and enable TLS 1.1 and 1.2, the site refuses to work.  I'm using the "DisabledByDefault" and "Enabled" registry keys to add the TLS 1.1 and 1.2 functionality. The kicker is that I have all 3 applications combined on another VM and that one works fine in TLS 1.2.  It's just the separated VMs that won't work.  I suspect the issue lies with IIS because it doesn't even bring up the pop-up window for choosing which user certificate to use, which that is handled by IIS, not Tomcat.  I've compared all the settings between the working IIS and the non-working IIS and I can't find anything different.  I would love to get some ideas of what to look for next.  Thanks in advance!

I've got a problem in my application stack.  .Net website SiteA on server-farm A calles Site-B website on server-farm B throught a Citrix Netscaler Load Balancer on a static file ressource, in our case a .json file. Sometimes we get a http-405 back.

I've used MS Network monitor on Server-Farm A, and can see the valid http-request going towards server-farmB.

47 45 54 20 2F 61 73 73 65 74 2D 6D 61 6E 69 66 65 73 74 2E 6A 73 6F 6E 20 48 54 54 50 2F 31 2E 31 0D 0A 48 6F 73 74
GET /asset-manifest.json HTTP/1.1..Host

On Server-Farm B, i also used MS Network Monitor, and here i can also see the valid http-request entering the destination server.

47 45 54 20 2F 61 73 73 65 74 2D 6D 61 6E 69 66 65 73 74 2E 6A 73 6F 6E 20 48 54 54 50 2F 31 2E 31 0D 0A 48 6F 73 74 3A 
GET /asset-manifest.json HTTP/1.1..Host:

But when doing a TRACE in IIS, the request-Verb is reduced from GET to 'T'. Our IIS installation is completly generic, only URLRewrite 2.0 is installed.

SiteId="22", AppPoolId="<domain>", ConnId="1612948779", RawConnId="0", RequestURL="<domain>:80/asset-manifest.json",RequestVerb="T"

Anyone has any idea why this is happening and how to solve this?

Hi,

my IIS site current stop working. I'm not sure what I have done but it kept reporting 500.0 error. I have also checked the httperr log and it just show that the connection has been canceled. But I can't find any document about this error. The binding just works fine and firewall has been disabled.

Thanks in advance.

I have an IIS 10 revrese proxy to a tomcat app which requires larger than 2gb file uploads. Is there a way I can bypass the system.web/httpRuntime.maxRequestLength 2gb max to at least get to the 4gb limit set by request filtering?

Setup:

Windows Server 2016
IIS 10
ARR 3.1
URL Rewrite 2.1
8gb Memory

We have a WCF app running on IIS on Windows Server 2016. Everything works fine until we realized some requests fail with status code 500. I set up failed request tracing on IIS and realized IIS responds with following error:

The I/O operation has been aborted because of either a thread exit or an application request. (0x800703e3)

There is not much on the Internet about this error. I found some older sources pointing to a Windows Server 2008 bug, but I would doubt it is the case. Has anyone else experienced this? What other things I could do to troubleshoot this issue?

HI ,

We are getting  401.2 unauthorized error due to invalid credentials when ever Domain controller is patched and rebooted.  To resolve the issue we are doing IIS reset.

IIS application using anonymous authentication with domain account identity 

We have 10 DC 's in our environment and IIS application application should pick up other available DC when primary DC is unavailable

can anyone help to resolve this ?
