Microsoft IIS Web Server





IIS is Internet Information Services, the web server included with Windows Server operating systems. All current versions are built on a modular architecture; modules can be added or removed individually so that those required for specific functionality are installed. The full installation of IIS includes HTTP, security, content, compression, caching, logging and diagnostics.

So I allowed one of my website domains to lapse into inactive status. It is now in the "redemption period" and I've changed my mind about letting it go; I'd like to keep it. It will cost me nearly $100 to get it out of redemption though. So, if I just let it completely expire, I might be able to pick it back up for cheap (if I'm quick about picking it up early on the day that it's made available to everyone else). How will I know which day that is (I tried "whois.com" but could only find the dates of Registration and Expiration - and the expiration date was some time ago). Also, Whois.com still shows me as the owner.

Any other advise, about my attempting to do this, would be greatly appreciated.

Thanks in advance.

Looking at the worker processes in IIS for the website, the time lapsed seems to be quite high and the cpu usage is also very high.
The webiste is down as well. Please help how to resolve this issue.

I have a virtual directory on my server called "uploads". The directory points to a specified folder outside the www-root.
How do I link to files in the virtual folder as an URL? I suppose I have to build in server.mappath somehow, but I can't make it work.
Any good advice? :-)


I have tried almost everything on the Internet, I am not sure what am still missing.
PC: Windows 10
Router: Port forward enabled with UnPnP

The webserver is a Datasnap REST webserver, (might be irrelevant), hosted with IIS on windows 10 PC, and its accessible to localhost as well as different computer on same network, However its failed to get connect to when accessible via public ip:port  even on same pc.
Tested the port which is listening correctly. I put firewall and Antivirus off for the test.

Please help.

Thanks and Regards,
I find myself in a remote northern community with no road access except for a few weeks over the ice during the winter.  Oxford House, Manitoba, Canada.

I just purchased a new satellite dish from Xplornet which promised me 5 Mbps.  Unfortunately, the most I've ever seen is 1.2 Mbps, early in the morning.  Late in the afternoon, it degrades to 500 Kbps or less.  I'm paying $100 per month for this service.  The technician at Xplornet explains that the slow speed is a function of how many people in the community are using the service during the day.  Really?  I'm sharing the service with the whole community?  (It's a community of 3,000).

My neighbour has a business service.  He's paying $2500 per month, and he's getting 9 Mbps.  I have been told that his service (from a company called Galaxy) uses a very different technology.

Does anybody know what is the bottleneck with remote satellite Internet service, and are there any options between $100 per month and $2500 per month?  I'm the IT guy and I'm supposed to understand how this stuff works.

Is this the best way of redirecting pages (permanent 301 redirects) from the old location of the domain to a new site (same domain) within  ASP.NET MVC using c# or should i be creating list within a controller?


        <rule name="Name of page" stopProcessing="true">
          <match url="^Consultants.cshtml$" />
          <action type="Redirect" url="/Home/About" />
        <rule name="New rule" stopProcessing="true">
          <match url="^Consultants.cshtml$" />
          <action type="Redirect" url="/Home/About" />

Hi All,

I've saved a Visio 2016 file as a webpage, which works very well.

however, when I try to put it as an iframe on our intranet the links stop working.

If I browse the same file in the exact same location the li is work.

Any suggestions?

Hello Experts,

I have a web application that I would like to host on Windows Server 2016 using IIS? The following steps below have already been taken.

Steps already taken:

- Setup Windows Server 2016
- Added the Web Server Role
- Installed .NET Core Windows Server Hosting bundle

I have so far followed this article https://docs.microsoft.com/en-us/aspnet/core/publishing/iis?tabs=aspnetcore2x to the step Application configuration but get lost from there.
Greetings all

I'm running SharePoint 2013 Foundation inside a domain and I'm trying to make it accessible from the internet for a few individuals. So I opened up port 8181 on my router and pointed to the server and I added a binding for 8181 to IIS and reset IIS. Now when I browse to the address "http://IPADDESS:8181/sites/domain/sitepages/home.aspx" it asks me for authentication, which is good, but all I get is 404 File Not Found.  I haven't added any additional AAM's.

Do I need to add and AAM? And what zone would it be in? Do I need to do anything else?

Can some body throw good article on IIS WEBSERVER,

I have interview need to know aplication pool, worker process.

how the basic architecture works , what components are important
Good day,

I've been asked to expand my Nagios unix monitoring with a couple of dozen Microsoft IIS servers on a very short notice. My setup uses NRPE and rather than having to (powershell) script everything from scratch I was wondering if anyone can point me to some  descent relevant Nagios IIS checks (Preferably under the GNU General Public License).  I use nsclient++  to monitor Windows servers.

Much appreciated,

I have created a PHP page that interrogates an SQL server returning an array.

I need to restrict access to certain users/groups with in active directory. I have achieved this using Authorisation rules within iis, however by turning off allow anonymous users.

I get the following message

Array ( [0] => Array ( [0] => 28000 [SQLSTATE] => 28000 [1] => 18456 [code] => 18456 [2] => [Microsoft][ODBC Driver 13 for SQL Server][SQL Server]Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'. [message] => [Microsoft][ODBC Driver 13 for SQL Server][SQL Server]Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'. ) [1] => Array ( [0] => 28000 [SQLSTATE] => 28000 [1] => 18456 [code] => 18456 [2] => [Microsoft][ODBC Driver 13 for SQL Server][SQL Server]Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'. [message] => [Microsoft][ODBC Driver 13 for SQL Server][SQL Server]Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'. ) )
I installed a web application on my local laptop, then I need to open up IIS to work with the Authentication type.
So if I go into IIS and right click on the name of my website (World globe icon next to site), I see icons to the left in a window.
If I double click on the "Authentication" icon, the only type of authentication that is listed is "Anonymous Authentication".
I am actually expecting to see other forms of authentication, listed but they are not? Why don't I get a list of other types of authentication? I also have three other web sites installed on my laptop, and those also only list Anonymous application.

If I look on a local server the list of authentication types, includes a list of 5 types (See below). So why aren't these authentication types listed on my laptop?

Anonymous Authentication
ASP.NET Impersonation
Basic Authentication
Digest Authentication.
Forms Authentication
Windows Authentication
I'm trying to browse to my new website and I get the following error:  HTTP Error 404.17 - Not Found "The requested content appears to be script and will not be served by the static file handler."

Any suggestions?  I'm using a Windows Server 2012 IIS 8.5.
Points of My Scenario:
1. I am troubleshooting CRM Dynamics website failure, which occurred after 3 un-installable Windows updates (KB4025337, KB4022722, and KB4034679).

2. Users get the following error when attempting to connect to website: "This page cannot be displayed. Turn on TLS1.0, TLS 1.1, and TLS 1.2 in Advanced settings and try connecting to <https://website> again"

3. TLS 1.0, TLS 1.1, and TLS 1.2 were all always checked (turned on) in the Advanced tab of the Internet Options dialog box.

4. In IIS (on a Windows Server 2008 R2 SP1 member server) the "Microsoft Dynamics CRM" website bindings include http (over port 'wxyz'), and https (over port 'efgh').

5. Surprisingly, the "Browse *:wxyz (http)" link works, WHILE the "Browse a.b.c.d:efgh (https)" link  fails with the generic error "Internet Explorer cannot display the webpage"

6. When the user tests the non-SSL version of the website, (s)he gets the error "Not Authorized. HTTP Error 401. The requested resource requires user authentication."

7. The https (SSL) and the http (regular, unsecure) links are identical - so, whereas the https (SSL) link complains about the absence of settings that are truly present, http complains that the user is not authorized.

QUESTION: What shall I do next to troubleshoot/resolve this failure of the CRM Dynamics website?

I am grateful for any help I can get. :-)

Hello All;

The exchange server is configured for an anonymous relay, my app only uses authenticated smtp via Username and Password or APOP.

So my options as I see it if possible...
Can I setup an authenticated SMTP relay in my IIS that sends anonymously to their relay?
Can I recommend that they add an authenticated relay for my mailbox on an exclusive port to ensure it does not hurt their configurations?
Hi - I have a 2012 server setup as a Domain with RDS running.  I have a VM on the server which is added to the domain and have given user access to this.  

I have a CA certificate with the subject mail.domainname.com  which is trusted on the RD Gateway Certificates in Connection Broker single sign on/ Publishing/ RD Web Access and RD Gateway.

My RD Gateway has Use these RD Server setting  - Server name mail.domainname.com with Logon method set to Password Auth and a tick in Use RD Gateway credentials.

I have installed the cert on the local Win 7 PC and checked it is in MMC - also checked thumbprint to confirm correct cert.  All ok

Now my Issue -

From my remote PC I can login to RDWeb (https://mail.domainname.com/rdweb - no problems and no certificate issues - and it shows connected to RemoteApp and Desktop Connections in bottom right hand corner.

Now I choose connect to a remote PC -

Type in PC Name  and choose connect -
I then get the windows security popup with Enter your Credentials - domainname\username and password

Input and click ok - and it says starting initiating remote session

Then - A box pos up saying - Your computer cant connect to the remote computer because the Remote Desktop Gateway server address in unreachable or incorrect.  Type a valid Remote Desktop Gateway server address.

ok - so looking at my Remote desktop Connection it says the Gateway server is svr-servername.domainname.com  - which is the FQDN of the server.

So …
I need to redirect a website within IIS instead of using a DNS change.  What is the best way to do this?
I am trying to redirect a URL from http://www.rudythecarguy.com/ApplyNow.com to http://www.rudythecarguy.com/ApplyNow. I added the rewrite section below to the system.webserver section of the web.config, but it doesn't work. Is there a kind soul out there who can shed some light on this darkness?
Thank you.
        <rule name="RudyRedirect" stopProcessing="true">
          <match url="www.rudythecarguy.com/ApplyNow.com" />
          <action type="Redirect" url="www.rudythecarguy.com/ApplyNow" redirectType="Permanent" />
Currently in IIS, I have 3 URL Rewrite rules:
1.  Redirect http to https
2.  If they forget to put in the www in front of the domain name they are redirected to the correct site
(This is what I used:  doesn't match pattern  ^www\.([.a-zA-Z0-9]+)$)
3.  If they come in using www1 (which still exists), they are redirected to another URL

Now, they want to start using subdomains (example:  clientname.domain.com)
What currently happens is rule #2 puts a www in front of the name because it doesn't have www.  
We have a lot of clients and they want a subdomain for each one.

Any ideas on how to accomplish this?
we have a number of internal applications which rely on IIS for the web server. These are only internal servers but we have noticed the 3rd parties whose apps we use have within the web root  some web.config12.bak type files. These do have hard coded DB and admin credentials within them so we would not want them exposed to any internal officers.

All servers are internal and not internet facing so the risk is limited to internal employees, and it is a small workforce with limited web server skills I would presume. The web root is hosted on the servers D:\, and the actual permissions on  the web root folders themselves only grant IIS_USERS group read on read & execute permissions. I typed the full path into a browser, e.g. \\server\app\live\admin\web.config12.bak and it returns a "404 - File or directory not found" error, even though I know it exists in that path. If I try a sample of other files in that directory such as styles.css, or a log txt file I know exists, my browser loads them up fine. So I am wondering if its something to do with the extension that causes the 404 error rather than ACL permissions preventing their download. As the ACL seems to be the same for all files in that directory, so it must be an IIS additional security control, perhaps.

I just need to be sure this would be consistent for all internal employees, that nobody could download a copy of these web config backup files, or if its the behavior of the browser preventing the …
