Error access Certsrv site from 2008 server to 2003 CA

So we recently had to request a certificate from a Windows 2008 R2 Server from our internal Windows 2003 Enterprise Certificate Authority. When we hit the https://server/certsrv site we got this error:

 

Microsoft Active Directory Certificate Services  —   
Error
The certificate enrollment page you are attempting to access cannot be used with this version of Windows. To enable Web certificate enrollment for clients running Windows Vista, your administrator must update all Windows CA Web enrollment pages. To learn more about this issue and the steps needed to update Web enrollment pages to support all versions of Windows, see:

Well after doing some searching, http://en-us.sysadmins.lv/Lists/Posts/Post.aspx?ID=53, I found that you need to do some uninstalling and re-installing of patches for the CA server.

Here are the steps to get it working:

To work around this issue you must follow the steps described below:

  1. Uninstall KB2518295 from Add or Remove Programs applet.
    Note: by default security updates are not shown in Add or Remove Programs applet. Mark Show Updates check-box.
  2. Install KB922706 update. Use the links below to download appropriate update:
    Download link for Windows Server 2003 x86
    Download link for Windows Server 2003 x64
  3. Install MS11-051 security patch. Use the links below to download appropriate update:
    Download link for Windows Server 2003 x86
    Download link for Windows Server 2003 x64

After update installation you may need to restart web site that serves enrollment web pages. To do that, do the following:

  1. In the Start –> Administrative Tools select Internet Information Services (IIS) Manager.
  2. In the opened console, expand Computer Name\Web Sites node.
  3. Select Default Web Site entry.
  4. In the Actions menu, select Stop and then click Start from the Actions menu.
