Solution:
The application pool account needs to be given launch & activate permission to the DCOM 'osearch' service. In my case it was the network service which was getting accessed denied. I had to give it the permissions and there were no errors in the eventviewer.

• Start -> Run -> DCOMCNFG
• Component Services ->Computers->My Computer->DCOM Config
• Look for osearch and right click it to give lauch, activate permissions to the desired account
• Sometimes you need to give the IISWAM REG ADMIN service.

Hope this helps someone.
