To prevent click-jacking, add the HTTP response header “X-Frame-Options” into IIS for websites and or Exchange OWA:

– Open IIS Manager and click on the server name in the left column.  Drill down if you only want to apply to one website.
– In Features View, double-click HTTP Response Headers.
– On the HTTP Response Headers page, in the Actions pane, click Add.
– In the Add Custom HTTP Response Header dialog box, add a header called “X-FRAME-OPTIONS”, and assign it’s value to “SAMEORIGIN”.

Server Connection: Not Connected to SRM server

December 17th, 2015 3 comments

I was unable to find this problem documented anywhere, though there was a reference to it on another blog here:


The problem presents itself this way, looking at SRM in the web client in version 5.5 of VMWare, 5.8.1 of SRM:


As you can see, client connection shows as connected, however server connection shows as “Not Connected to SRM server”.  It wasn’t obvious to me, but what this means is the sites are not connecting to each other, even though they are paired and everything else looks green.

Additionally you will notice that the option to replicate changes to the secondary site before failover will be grayed out.

I spent several days troubleshooting this before I found an indicator in the logs that pointed to certificate errors.  I believe that if I was able to un-pair and then re-pair the sites, this would have been resolved.  However in order to un pair sites, you must first delete the recovery plans and protection groups.  When attempting to delete, the status would say deleting and never complete.

Ultimately to resolve I uninstalled SRM at both sites, deleting all data from database.  I then reinstalled and reconfigured SRM, protection groups, and recovery plans.
