Hi,

I have an Application Pool (IIS 8.5 - Server 2012 R2) which is using the "IIS AppPool\ApplicationPoolIdentity". For example it is the pool "abc". w3wp.exe is running with "IIS AppPool\abc". My Website "abc" on drive F: have only read permission for "IIS AppPool\abc". I tested this, I can't access from other pools to the "abc" website.

The "IIS AppPool\ApplicationPoolIdentity" - User is normally in the group of "USERS". When I install Windows, the drive c: got automatically permissions for the group "USERS", which means that every User in the group "USERS" can access most of the files and folders on drive C:

My Question:
The Pool-User "IIS AppPool\abc" should only have permissions to files/folders on drive C: which are really needed for the functionality of the IIS. (The User schould NOT have access to C:\Intel for example).

So what can i do? Can i remove the "IIS AppPool\abc" from the group of "USERS"?
Removing the permissions from drive C: would be difficult, because windows will not let me do that for all folders on C:

Domsi

  I have two websites namely Website1 and Website2 hosted in IIS.

1.I have hosted two WCF services using Net Tcp binding in these two websites namely Service1 and Service2.

2.The two services are running on the same port i.,e 808.

3.Next I have created two clients to access the services.

4.From the first client I am able to access the first client properly.

5.But when I give the second service into second client and update the service reference, it is hitting the First Service only i.e,.(Service1) but the same works if I give different ports for two different services.

<endpoint address="net.tcp://mach04.local:808/Application/Service2.svc"

behaviorConfiguration="ClientBehaviour" binding="netTcpBinding" bindingConfiguration="NetTcpConfiguration" contract="Service2.IStorage2" name="Service2NetTcp">

        <identity>

          <servicePrincipalName value="host/mach04.local" />

        </identity>

      </endpoint>

Is this a limitation of net tcp binding to use different ports for sites. Any solution for this?

Hi

I've got a very bizarre situation. It appears that, when I load a webpage to my browser,
multiple instances (at least 2) are starting up. The app loads and runs fine on a
Windows XP box, but when I try to run it on my Windows 8 laptop it would seem that
more than one startup event is taking place and causing all kinds of collisions. This
is happening with both Firefox and IE.

To verify this behavior, I placed a static int within a class, checked it to see if its value
is greater than zero, throw an exception if it is, then increment the int.

Of course, the exception is thrown.

What's very weird about this is that there is no multi-threading/multi-tasking involved.

I'm thinking that this is an issue with IIS and the way that I have it configured.

The truth is that I'm pretty much clueless about IIS.

Any help with this would be very much appreciated.

THANKS!

Hello,

I have a 2012 R2 server with the following.

PHP Version 5.5.17

MediaWiki 1.23.5

Using FastCGI and MySQL 5.6 Community

I haven't enabled any Short URL Rewrite rules.

for some reason on a fresh build of mediawiki, as well as an upgrade from our existing I am seeing the same problem on this server, as well as doing the same build on a 2008R2 server under iis 7.5

Behavior is as follows, navigate to the server host name and since I have it as the default site for port 80 I don't have any semi colons for port reference in the URL. The page comes back fine and I see my CSS and Java has loaded.

I click on a link in the site and typically still see everything just fine.

Do a page refresh with the browser, regardless of browser type IE, Chrome etc and the page loses CSS and Java.

Usually I do another page refresh and its back but seems like it might only be the CSS and not Java.

Then refresh again and its all gone again.

Anyone have any luck doing a basic install of Mediawiki on IIS 7.5 or 8?

Hello,

I changed my php version from x86 to x64 on my development pc and I found x64 version for all my loaded extensions but imagick is causing troubles.

The minute I enable it in php.ini the I get HTTP 500 error (even with php info), and in my php error log I see this:

PHP Warning:  PHP Startup:  in Unknown on line 0
PHP Fatal error:  Allowed memory size of X bytes exhausted (tried to allocate X bytes) in Unknown on line 0

of course X would be the size of the memory, I just shortend it.

Every time it tries to allocate a different amount of memory and I get this error even if the memory limit higher then the size it tries to allocate.

I tried to update imagick binaries to 6.8.9-8-Q16-x64-dll, I re-downloaded thephp_imagick-3.1.2-5.6-nts-vc11-x64.dll from pear.php.net but it didn't help.

With the x86 version of PHP and imagick everithing works fine, so I don't have a clue why is this happening.

I tried to disable extensions one by one and left imagick the only one enabled but thats doesn't make any difference.

these are my php settings:

memory_limit = 256M
cgi.force_redirect = 0
cgi.fix_pathinfo = 1
fastcgi.impersonate = 1
fastcgi.logging = 0
max_execution_time = 300
date.timezone = Europe/Budapest

[PHP_WINCACHE]
extension=php_wincache.dll

[PHP_IMAGICK]
extension=php_imagick.dll

[SourceGuardian]
extension=ixed.5.6.win

Is there any way to make imagick work with PHP x64?

Oh and of course Imagick and php are added to path.

I have an error message on my application. I use windows 7 with IIS 7.5 and .net 4.5. Does anyone have any idea?

Hello, I am having some issues relating to IIS 7.5 and am wondering if there's a way I can make it a bit more user-friendly. I've developed/am developing a local intranet site for the company at which I work, and I have it setup to use Windows authentication to allow access to the site, period. My main file is index.php, and I use a case statement to determine what "page" it's on (i.e., ?p=about is the about page, ?p=docs is the documentation page, etc.). Granted, I know that if I used multiple files instead of mostly in the same file, permissions could be a bit easier - but I'd rather not do it this way.

I have an SQL database setup with accounts for admins and managers, and every user has a "permissions" field in their row. If it's greater than or equal to 4, they are an admin, and 5 is a Super User essentially. Basically, what I'm wondering is if there's a way to use Windows permissions (such as what user group somebody's in) to access certain features of the site, such as a variable or a function of some sort.

For example, say that John Doe is part of the Administrators group on the Windows network (we're on a local domain here). He would therefore, since he is an admin, be able to access the Add Update and View Tickets pages. Now say Billy Bob (I'm not good with names) tries to access the same page. He's in the Default Users group, and should NOT be able to view tickets or add updates. That's what I'm going for here. Is there any way to do this with Windows permissions? I'm using PHP, but ASP is enabled if I should need it. As I've said, I've already got the username of the person logged in (as it asks them for their credentials once the site loads). What I need are the permissions from their respective user groups, and a way to access that using PHP. Any help would be appreciated.

I've searched high and low for this but am having trouble finding anything relating to it. Thank you.

Hi,

this is a fresh install of Windows Server 2012 R2, installed the W.P.I and then choose the PHP 5.6.0. If I try to 'http://ip_server' IIS works fine so I cretead a new file named 'C:\inetpub\wwwroot\teste.php' but when I tried to access 'http://ip_server/test.php' shows a message like this:

Does anyone idea about how to fix it?

I'm trying to take old URL's from a site built in Wordpress, and redirect them to the new pages on my IIS server. Some of them are working, and some are not. I've noticed that if the URL is a sub page, meaning it's using back slashes to separate the deeper pages, it won't work and will break my site.

Can anyone tell me how to redirect a page that looks like this?

example.com/areas-served/texas/ to example.com/areas-served/texas.aspx

I would really appreciate some help!

I have a WCF service that will have its own app pool and the pool will need to execute as a specific domain account.  The service will be access from an ASP.net app on the same server.  Both will use windows authentication, but I want to limit access to the service and the app to a specific domain group.

Are .NET authorization rules what I need to look at?

Will the request from the web app to the WCF service come in with the users credentials or as "network service"?

I wont wont to set a specific identity on the app pool for the web app.

hi,

We are currently developing a business ASP.NET application that you can only access from a public IP address (ie the internet) even if we are on the same network of portal web server.

The problem is that we want to access to the web server does not come only from the internet but:

1 If access to the portal is inside the corporate network it is accessed by the internal corporate network and no internet. 
2 If you have access from the external network that is Internet access

How can I configure IIS to such a configuration ??

Thank you in advance.

I have 1 ARR-Server with IIS 7 WebFarmFramework and Application Request Routing. In my Farm i have 4 Live-Server (LiveServer1, LiveServer2, ...) with the same content and the first Server is marked as primary. At Port 80 is a Startpage and a Health-Status-Page.

Then I have 20+ WCF-Services which listen at TCP Port 808. For communication i use Net.Tcp.

When i use my domain for example http://test.com which is mapped on my ARR Server i will be routed of one of my 4 Servers.

This works all fine.

My Problem is that when i use net.tcp://test.com:808/WCFServies/Servicexyz/Service.svc the WebFarm do do not route me to my Live-Server.

When i use: net.tcp://LiveServer1:808/WCFServies/Servicexyz/Service.svc i can connect to the Service.

Hi,

I've been on this problem for hours now ... And I'm pretty sure I'm doing something wrong but I don't know what ! My hope is to find someone nice enough to help me or said me : "just click here and apply".

On my IIS 7, I enabled a directory browsing with physical and virtual directory. Each directory is  restricted with ACL rights (NTFS) and the Digest authentication is activated and linked to my AD. ACL are ok because I check it over SMB and the Digest authentication is ok too.

But what I want is to apply the ACL rights to the authenticated user. Actually it is not the case, if the user exist in AD then he can browse every files in the directory linsting like the user used to run the IIS Application (in my case Administrator).

I don't know what to do to resolve this.

Best regards,

I've had IIS 7.5 shared config websites running for over two years without issue.  Previously their configs were held on a 2008 R2 Enterprise Cluster.   The admin who maintains the cluster, migrated to a 2012 R2 Standard Cluster.  Immediately on failover of the new cluster the IIS sites were failing.  I cached the configs, which allowed the sites to appear up, but the virtual folders within the websites, which are held on the 2012 cluster are inaccessible, so a portion of the web application does not function, following failover of the 2012 cluster.   

Conversely while I have 3 website servers, hosting identical application, one of those servers I do not use a shared config.  That server does not require a reboot following the failover, and the virtual folders appear to be accessed by the application just fine.

Details:

Web Configs and virtual directories are accessed via DFS

Each of the nodes of the 2012 R2 cluster runs DFS

\\domainName.com\DFSWebShare\IISConfigs

\\domainName.com\DFSWebShare\WebVirtualDirectory1

\\domainName.com\DFSWebShare\WebVirtualDirectory2

Any ideas?

Hello,

I don't know if this is the right place to post my problem.

I spent a lot of hours to try to enable cross site request on my asp net mvc web site, on windows server 2012 r2.

The same web site on windows server 2008 give me no problem.

I try in the web config to insert

..<remove name="OPTIONSVerbHandler"/>
...

but with no success.

I try to insert

<httpProtocol><customHeaders><add name="Access-Control-Allow-Origin" value="*"/><add name="Access-Control-Allow-Headers" value="Content-Type"/><add name="Access-Control-Allow-Methods" value="POST,GET,OPTIONS"/></customHeaders></httpProtocol>

and again without success.

Any help will be really appreciated

Hi

We have an IIS 7 web server that publishes a number of ASP.net web services and have a new requirement to process some messages and redirect others to a different endpoint, depending on the payload content.

I see this article on Redirection to another Web Site:

http://technet.microsoft.com/en-us/library/cc770409(v=ws.10).aspx

Q.1) Does Redirection work for ASP.Net Web Services?

Q.2) Is IIS 7 Redirection flexible/powerful enough to do the redirection optionally, based on payload content.

Q.2.a) If so, some pointers on how to get started would be helpful.

Thanks, Steve

In our production environment we are seeing HTTP_HOST server variable containing :443 in it.  This doesn't seem to be happening all the time. Isn't that variable suppose to contain only the host name and not the port. Am I understanding it incorrectly ? 

Hi,

I wanted to delegate the HTTP errors to end users. But when I load the web.config in IIS from one of the sites I now get the message "Lock violation" with the line number where this configuration parameter is set:

<error statusCode="404" prefixLanguageFilePath="" path="/default.aspx" responseMode="ExecuteURL"/>

My server config file contains this setup:

        <httpErrors lockAllAttributesExcept="errorMode" lockElements="error">
            <error statusCode="401" prefixLanguageFilePath="%SystemDrive%\inetpub\custerr" path="401.htm" />
            <error statusCode="403" prefixLanguageFilePath="%SystemDrive%\inetpub\custerr" path="403.htm" />
            <error statusCode="404" prefixLanguageFilePath="%SystemDrive%\inetpub\custerr" path="404.htm" />
            <error statusCode="405" prefixLanguageFilePath="%SystemDrive%\inetpub\custerr" path="405.htm" />
            <error statusCode="406" prefixLanguageFilePath="%SystemDrive%\inetpub\custerr" path="406.htm" />
            <error statusCode="412" prefixLanguageFilePath="%SystemDrive%\inetpub\custerr" path="412.htm" />
            <error statusCode="500" prefixLanguageFilePath="%SystemDrive%\inetpub\custerr" path="500.htm" />
            <error statusCode="501" prefixLanguageFilePath="%SystemDrive%\inetpub\custerr" path="501.htm" />
            <error statusCode="502" prefixLanguageFilePath="%SystemDrive%\inetpub\custerr" path="502.htm" />
        </httpErrors>

and

<section name="httpErrors" overrideModeDefault="Allow" />

When I change the first line to "<httpErrors lockAttributes="allowAbsolutePathsWhenDelegated">" it works...

My question is what is actual correct? I want to delegate HTTP errors, but only allow changes to the status codes in the list above, and they only can define the type (file/url/local), path, prefix. 

How do I properly lock this configuration?

Hi,

When I try to open a site with WebMatrix 3.0 I get "webMatrix has stopped working" . "A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available" When clicked "Close program" program closes.

This had been working fine up until couple of days ago.

IIS keeps running and we can access the Wordpress site. Webmatrix is running on a Windowa 8.1 with IE 11.

On the event viewer we get the below listed three errors. Appreciate anyone's thoughts to troubleshoot and get this sorted.
