The search service is not able to connect to the machine

Error: The search service is not able to connect to the machine that hosts the administration component. Verify that the administration component ‘ ′ in search application ‘Search Service Application’ is in a good state and try again. 

After surfing on net,I found Neel's useful link which resolved my issue.

Cause: Search admin timer job was disabled

Below is the resolution, it might come in handy for all Sharepointer’s, if you all end up in the same situation

We enabled the timer job and restarted IIS and the SSA provisioned successfully.

Run below PS command to know the status, below was my scenario

Get-SPTimerJob job-application-server-admin-service | fl

Result ==> IsDisabled: True

Ran below PS command to enable the service. stop and start the timer and iis reset voila.. SSA was happy

Enable-SPTimerJob job-application-server-admin-service

Result ==> IsDisabled: False

Net Stop sptimerv4 

Net start sptimerv4 

iisreset

Then wait 1-2 min and try browsing to the SSA again
