In my case : The agent and RMS,MS are in the same domain. I am getting this issue with 4-5 agent servers not for all the agents. Please suggest how to fix it.

This is expected for agents that are not part of the same forest as the SCOM management servers. Certificates should be used for agent auth. If you are getting this on agents that are part of the same AD domain or forest as your SCOM servers, then your AD is broken and Kerberos isn't working. If you have agents in a different forest, but are depending on a Kerberos enabled trust between forests, this breaks easily and I recommend always using certificate auth when not part of the same forest.
