Lync 2010 Installation Problem

Question:

I'm having a strange problem when installing Lync 2010 on a new server build. I get through all the prerequisite steps and topology publishing just fine. I then move to the "Install or Update Lync Server System" section. From here Step 1, 2, and 3 all complete successfully with no errors.

I run Step 4 and the Lync services sort of start -
Lync Server Audio Test Service: Started
Lync Server File Transfer Agent: Started
Lync Server Front-End: Not Started
Lync Server IM Conferencing: Started
Lync Sever Master Replicator Agent: Started
Lync Server Replicator Agent: Started

When I try to start the Front End service: Windows could not start the Lync Server Front-End on Local Computer. For more information, review the System Event Log. If this is a non-Microsoft service, please contact the service vendor, and refer to service-specific error code -1008124830.

The event viewer shows this: Log Name:      Lync Server

Error #2
A component could not be started.  The service has to stop.

Component: Live Communications Applications Module  Error code: C3F2765F!_HRX! (APIEM_E_ESBASE_MISSING!_HRM!)

 

My Solution : -  Try to restart Front End Service, If it works then your problem will be resolved. Otherwise it may lead to rebuild of server.
