Sothink Video Encoder for Adobe Flash under Windows 2008 Server

Need help getting the Sothink Video Encoder for Adobe Flash working under W2K8 or W2K8 R2 server?

Here is how to properly configure your server:

  1. Install the Sothink Video Encoder for Adobe Flash software and register it using your registration key.
  2. In the destination folder for the videos, you will need to grant {machinename}\IUSR full control.
  3. the MyRequest.dll file (for ASP) won’t work properly, so if you are using ASP, you will need to use some other method to upload files to the server.  One good choice is ASPUPLOAD.COM
  4. Presuming you have already setup a site under the IIS 7.5 management tool, you need to change the pool to LOCAL SYSTEM.  Do this by locating the application pool for this site, then click ADVANCED SETTINGS (on the right nav) and under PROCESS MODEL, for Identity, select LOCALSYSTEM
  5. Click OK to close out of the property page above, then click RECYCLE
  6. You will need to grant scripts and executables property to the site.  It’s different under IIS 7 and IIS 7.5 to do this… so on the site home, open HANDLER MAPPINGS, and click “edit feature permissions” and check execute.  Then click OK and exit out.
  7. I would advise at this point to restart IIS on this box by clicking the server name and then RESTART in the right nav.
  8. If you’ve done all the above properly, you should have no problems encoding videos using Sothink Video Encoder for Adobe Flash on a Windows 2008 server.


IIS 7 and IIS 7.5 script map .htm to asp.dll

I recently upgraded a site from a Windows 2003 server to a Windows 2008 R2 Web Server and needed to be able to continue running .htm files through the ASP engine, because many of the pages on the site comingled ASP and HTM.
After spending about 3 hours looking into this, I finally worked out the process (below). I hope this gives some of you a time savings!
  1. Make sure that ASP is installed on IIS 7 or IIS 7.5 (obviously)
  2. Setup your web site
  3. Your ASP files should work normally
  4. to allow your .htm files to run through the ASP engine, do the following
  5. On your IIS 7 or IIS 7.5 server, go into the C:\Windows\System32\inetsrv\config directory and edit the file applicationHost.config (you will need to do this in administrator mode, or do it from a different computer networking over to that server, otherwise Windows will protect that file and won’t allow you to change it.)
  6. Scroll all the way to the bottom and look for the section that corresponds to your web site <location path=”Your Web Site”>
  7. Change/edit the code block to add in the HANDLERS and HTM map below
  8. <location path="Your Web Site">
    <asp appAllowClientDebug="true" scriptErrorSentToBrowser="true" />
    <add name="htm" path="*.htm" verb="*" modules="IsapiModule" 
           scriptProcessor="%windir%\system32\inetsrv\asp.dll" resourceType="File" />
  9. Save the file.
  10. Restart the web server in the IIS Manager by right clicking the server name.
  11. Test your site. .HTM pages should now work as ASP files by running through the ASP.DLL

WordPress Windows 2008 Web Server R2 IIS 7.5 setup

I thought I would share a few important tips on getting WordPress 3.x to work properly – with PERMALINKS / SEO friendly URL’s.  It’s taken me a lot of trial and error to figure out the finer points, but assuming you can get it installed, these tips should help you get it 100% functional.

  1. to install, use the Microsoft Platform Installer 2.0, and let it do the work of installing PHP, WordPress etc.  IT IS FANTASIC!!! It will automatically setup PHP/FASTCGI for you and it is slick!  You can access the direct link to install WordPress on IIS here
  2. Secondly, I am going to make an assumption you are installing this as a subdirectory on your root site, such as  If you are installing this to the root the same directions will basically apply but you’ll need to figure out which setting will need to be adjusted to put WP on the root.
  3. Third, we use a dedicated MySQL 5.x box, so we don’t install MySQL as part of the MPI 2.0 install (from step 1).  If you don’t already have a MySQL server you’ll need to let it install that as well, or make a new empty database on your MySQL box and use that info as part of the install process.  For security and speed reasons, a dedicated server for MySQL is the best choice, but not everyone has the resouces to permit a dedicated server.
  4. Under IIS 7.0 or 7.5, make sure you have downloaded and installed the free URL REWRITE 2.0 add-in for IIS.  This is a free download here:
  5. PERMALINKS.  Once you get WP installed and are able to login to the admin interface, it’s pretty simple to get permalinks running.
    1. in the WP admin, go to SETTINGS->Permalinks.  We chose to use the “DAY AND NAME” setting.  Any other setting is your choice.  Pick a setting and click save changes.
    2. make sure you have a web.config file in your /blog/ subdirectory. 
    3. here is what your web.config file should look like – customized just for WP 3.0 in the /blog/ subdirectory (below).  (Download a ZIPPED copy of my file here)
    4. <?xml version=”1.0″ encoding=”UTF-8″?>
          <httpErrors errorMode=”Custom” />
             <rule name=”Main Rule” stopProcessing=”true”>
              <match url=”.*” />
              <conditions logicalGrouping=”MatchAll”>
               <add input=”{REQUEST_FILENAME}” matchType=”IsFile” negate=”true” />
               <add input=”{REQUEST_FILENAME}” matchType=”IsDirectory” negate=”true” />
             <action type=”Rewrite” url=”index.php” />
              <clear />
              <add value=”index.php” />
    5. Save this into your web.config file – this is all you need for WP running in the /blog/ directory.  Once you replace your file with this one your permalinks should work flawlessly.
  6. Troubleshooting.  One easy way to troubleshoot things with your WP install, is to enable DETAILED errormode.  To do this, edit your web.config file within the /blog/ folder and change just the one line above to this <httpErrors errorMode=”Detailed”/>  Of course when you are all done and going live with WP, change that line back to “Custom”
  7. Fixing permissions so that images/media/files uploaded via WordPress will properly render.  This is the fix for the infamous “500” error that is thrown when your server has wrong file permissions and the visual result is all the images you uploaded are “broken images” and won’t display. Also called HTTP Error 500.50 – URL Rewrite Module Error when you have Detailed errors on.
    1. Don’t sweat it, I will save you HOURS of time on this one.   Thanks to the article I found here after HOURS of tracking this issue down, this problem is caused because PHP first uploads the document to a temporary directory (by default C:\Windows\Temp), and then moves it from that directory to the actual /blog/wp-content/uploads/ subdirectory.  What happens is that because IIS does not have any permissions to your “C:\Windows\Temp” directory, when the file is uploaded there, then moved by PHP, the file inherits NO permissions.  So when IIS trys to serve out that file from your /blog/wp-content/uploads/subdirectory it throws a 500 error and that is actually a permissions error.
    2. The solution:  on the Windows\Temp folder, grant “modify” permissions to both IUSR and {servername}\IIS_IUSRS user accounts. 
    3. Now when you upload files via PHP and PHP moves them to the correct directory, the files will have the correct permissions and can be accessed.
    4. Important note #1:  If you already have uploaded files and are getting the dreaded broken images issue, go to the /blog/wp-content/uploads/directory and replace/update the permissions to add access for both user accounts noted above.  That will solve that issue.
    5. Important note #2: as with any change off the defaults for Windows, you do this AT YOUR OWN RISK.  It’s up to you if you want to grant the Windows\Temp directory permissions for those two accounts.  If you don’t PHP won’t be able to upload without the 500 issue (unless you move the PHP temp folder elsewhere and grant those accounts access to the other folder).  Do these changes at your own risk… I cannot and won’t take any responsiblity for your systems.  Please know what you are doing.

Best of luck on your Windows 2008 R2 IIS 7.5 WordPress install. We use it here and it is fantastic!

Classic ASP file upload limit of 200kb in IIS 7

During the process of migrating a site to IIS 7 we came across an issue with Classic ASP file uploads throwing 500 errors when larger than 200kb. There is an EASY fix for this.

In IIS 7, click your site and expand it then click the ASP icon.

Expand the Limits Properties icon, and change the value in the “Maximum Requesting Entity Body Limit” to a value larger than 200000 (which is about 200kb). 2000000 would be roughly 2mb, 20000000 would be 20mb.

Click the APPLY button. That’s it!

Serve static content from a cookieless domain – Google Page Speed Tip

Ok, so you are using the Google Page Speed plugin for Firefox and you can’t figure out how to clear the “Serve the following static resources from a domain that doesn’t set cookies” issue so that you score better…

First off, since we are using the Windows platform for our hosting, this entire post is making a big assumption you are too. If you are using some other platform or don’t have complete console or remote desktop access to your server, you can read on, but you’ll need to figure out this on your own.

The main thing you need to do is to REGISTER A NEW DOMAIN – or use one you’ve never used before – to specifically use for image and non-html things like JS and CSS.

If the web site is at you should register or something similar. YOU MUST register or use a completely different domain name than the base site.

Why is this? Because the way browsers store and cache cookies locally, even if you create a subdomain of your existing site, like, the Google Page Speed score will still detect that that domain accepts cookies, and this will not suffice. Pick a domain that you’ve never used or hosted before and this will work fine. Keep in mind your web site visitors are NEVER going to know your images on are a different domain unless they start poking around in your HTML source code anyways.

This specific information will reference IIS 7.0, so if you are on an earlier version feel free to comment and I will see if I can pass along the settings.

So now that you’ve got your new and unused domain name ready to do, setup a new web site instance on your web server, preferably the latest OS such as Windows 2008 server.

DO NOT START the site after you set it up. Bind the site IP to the new domain name.

Bind it to the NO-MANAGED-CODE Application pool.

On this specific site you created, double click HANDLER MAPPINGS. Remove ASP, ASP.NET, PHP or any other script based handlers that appear here. ISAPI ones are OK to keep.

Start the web site instance.

You’ll now need to copy over your images to the new domain (via FTP or however).

Copy the following types of files

  • All images – png, gif, jpg
  • CSS files
  • favicon.ico file
  • JS files

In your HTML on your base site you’ll need to update ALL the image, CSS, JS, Favicon, and JS references to point to the server. You should know how to do this if you can get this far. We are talking HTML 101 here… 🙂

If you’ve done this all properly, re-run the Google Page Speed plugin and it should remove these issues off your task list and change them to “green checks”. If it doesn’t you probably have some script engine enabled on the domain and it is setting a cookie automatically (like ASP.NET). Remove it off that site.

Here at Amixa we use a dedicated server with all the script engines (ASP, ASP.NET, etc.) completely disabled to “serve cookieless domain content”.

First access on ASPDOTNETSTOREFRONT on a W2K8 R2 server…

Ok, so you’ve completed your install of ASPDNSF 9.x onto a Windows 2008 R2 server, and when you first try to access the domain, you get this error:

Exporting IIS 7 web site settings…

Well, now that Microsoft is shipping Windows 2008 Server R2, we need to know how to (easily) migrate a site from one W2K8R2 machine to another, right?  Microsoft didn’t exactly make this an easy process because there is no built-in method in the IIS 7.0 GUI to do the site export.  So to do the export (and import on another IIS 7 box), you need to drop to a command line and run the following commands:

EXPORT site from IIS 7 (Windows 2008 R2 server)

%windir%\system32\inetsrv\AppCmd.exe LIST SITE "" /config /XML > D:\mysitesconfiguration.xml

IMPORT site into IIS 7.0 (after you have created the above export XML file…)

%windir%\system32\inetsrv\AppCmd.exe ADD SITE /IN < D:\mysitesconfiguration.xml

The last step is to create a new application pool and assign this IMPORTED site to the new application pool.

NOTES:  It is very important that you run this from a command prompt, not the “start bar box” on the Start Menu in Windows 2008 R2 Server.  Instead run the command prompt as Administrator and do this command by keying it in, or create a batch file and execute it as the administrator on that machine.

Disabling SSLv2 support in IIS

If you have undergone a “Trustkeeper Scan” and failed due to your Microsoft web server using SSLv2, then read on.

NOTE: PLEASE READ THIS POST IN OUR BLOG HERE.  It is TWO YEARS NEWER and simplifies most of the tasks regarding SSL settings.


SSLv2 is considered a “medium” security risk and will cause your scan to FAIL, so therefore to be PCI-DSS compliant (for credit card companies), you need to disable it via the registry on your Windows server running IIS 3 or later.

The easiest way to do this is to read this KB article from Microsoft.

In a nutshell, you need to go to this registry key


Then locate the SSL 2.0 key

  • Click on the “Server” node.
  • On the Edit menu, click Add Value.
  • In the Data Type list, click DWORD.
  • In the Value Name box, type Enabled, and then click OKNote: If this value is present, just double-click the value to edit its current value.
  • Type 00000000 in Binary Editor to set the value of the new key equal to “0”.
  • Click OK. Restart the computer
  • if applicable, reschedule the security scan
