IIS and Cache Permissions

I'm running Windows Server 2008 and IIS 7.5. I have PHP 5.39 installed and running (other websites running PHP fine).

When trying to install LHC, I originally got the "Make sure that cache/* is writable" error. So, I enabled modify/write permissions on the folder and subfolders for user IIS_IUSRS.

Now when going to maxedgeweb.com/lhc I'm getting the same error but on a subfolder:
    [message:protected] => Directory cache/cacheconfig/ not writable!
    [string:Exception:private] =>
    [code:protected] => 0
    [file:protected] => Z:\xxxxxxxxx\lhc\lib\core\lhtpl\tpl.php
    [line:protected] => 15
    [trace:Exception:private] => Array

The "xxxxx" are blanked out for security.

I have confirmed that the cacheconfig folder has the same permissions as the cache folder.

I've heard of others running LiveHelper on IIS successfully, so am I missing something?

Oh, and I have donated before. Love the product.

Thanks for your help!

Re: IIS and Cache Permissions

Ok, I found my own solution. It varies depending on how things are set up, so here are the instructions based on what you find.

I ended up adding write permissions to the user: IUSR.

The first thing to do is to create a simple PHP file on the concerned website. (It's important to create the file on the concerned website because each website can have a different setting.) The content of this file should be:

[== PHP ==]
<?php var_dump(ini_get('fastcgi.impersonate')); ?>

Navigate to this file using a browser.

** Scenario 1 **

If your browser shows :

[== Undefined ==]
string(1) "1"

Then, you need to execute the following command (you need to replace "Default Web Site" by the name you gave to your website in IIS). I found it easier to navigate to C:\windows\system32 to run appcmd.exe:

[== Undefined ==]
%windir%\system32\inetsrv\appcmd.exe list config "Default Web Site" /section:anonymousAuthentication

You will receive an answer which looks like this :

[== Undefined ==]
<system.webServer>
  <security>
    <authentication>
      <anonymousAuthentication enabled="true" userName="IUSR" />
    </authentication>
   </security>
</system.webServer>

The information you are looking for is the value of the username attribute of the anonymousAutthentification tag.

• If this value is not empty, its content is the name of the user you need to give write permissions to.

• If this value is empty or if the attribute is simply missing, you need to give write permissions to IIS AppPool\AppPoolName (replace "AppPoolName" with the name of your website's application pool).

** Scenario 2 **

If your browser shows :

[== Undefined ==]
string(1) "0"

You need to give write permissions to IIS AppPool\AppPoolName (replace "AppPoolName" with the name of your website's application pool).
