ActiveSync, OWA, EMC and IIS stopped working in Exchange Server 2010

When ActiveSync in Exchange Server 2010 becomes inoperable due to unknown reason, other applications that are linked up with Active Sync may become non-functional as well. In my case, I have stumbled upon where smart devices stopped synchronizing to Exchange Server 2010, Outlook Web App (OWA), Exchange Management Console (EMC) and Internet Information Services (IIS) also became inoperable.  Note that Microsoft Outlook is fully operational.


  • Navigate to C:\Windows\System32\inetsrv\config, locate applicationHost.config and rename to applicationHost.config.old

applicationhost location


  • Replace the file C:\Windows\System32\Inetsrv\Config\Applicationhost.config from a backup.
  • Open a command prompt and run iisreset to Reset the IIS Service.

Now, test the email flow from a smartphone. Access the OWA, open up EMC and IIS. They should all start working and be fully functional.

HTTP Error 503. The Service is unavailable – SharePoint 2010

Note:  This Tutorial is based on SBS 2011 Server – Sharepoint 2010 and it will also work on Windows Server 2008.

Have you seen the HTTP Error 503 in your browser when you’re trying to access your SharePoint site?

Here are the possible resolutions:

Option 1:  Make sure that all SBS Sharepoint application pools are “Started” and not “Stopped”.

To do this, locate Information Services (IIS) Manager (click on Start then Administrative Tools) from the Windows Server (SBS 2011 or 2008). Select Application Pools, then locate all SharePoint application pools, if they need to be Started, go to the Application Pool Tasks pane and select Start.

SSL Error: “The security certificate presented by this website was not issued by a trusted certificate authority.”

Installing a 3rd party SSL Certificate can be very frustrating, tedious process and things can go haywire unexpectedly. Have you tried re-keying/generating the Certificate Signing Request (CSR) then installing the SSL Certificate many times and was wondering why your server is rejecting it? I have experienced this annoying process and will not go through with this process again.

I found a great utility to alleviate my irritation in installing a SSL Certificate. DigiCert is a one stop shop to do repair, test and export your SSL certificate.

When you download DigiCertUtil simply open up the compressed file ( and double-click on the executable file (DigiCertUtil.exe) then you’ll see the list of all the Certificates, some with the yellow exclamation mark or a red X.

Image 1 – Click on the SSL padlock icon, select the Certificate that needs to be repaired then choose Repair Certificate

Now that you are aware on how to troubleshoot your SSL Certificate by using a DigiCert utility, this great utility will save you a lot of work and headaches. I’m quite impressed with the outcome.
