Hi Saravanan,
Agree with above comments. Check the communication troubleshooting links. If the communication is good but the clients are not getting the updates then download the sylink monitor tool from the below link,
http://www.symantec.com/docs/TECH103369
Before running the tool, set the below value on the registry key and proceed.
- Click Start > Run
- Type in: regedit and click OK
- Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\Symantec Endpoint Protection\SMC
- Double-click smc_debuglog_on
- Change the Value data to 1 and click OK
Run the tool --> Restart SMC
- Click Start > Run
- Type in: smc -stop and click OK
- Wait until the SEP icon disappears from the system tray. (Approximately thirty seconds.)
- Click Start > Run
- Type in: smc -start. Click OK.
Collect the log and post it.
Note:
- On a SEP 12.1 client, the Tamper Protection feature needs to be disabled before following these steps.
- You can also generate a SyLink log without using the tool:
Inside HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\Symantec Endpoint Protection\SMC\SYLINK\SyLink
set DumpSyLink (a REG_SZ value) to the file path where the log should go (e.g. c:\sylink.log).
smc.exe must be restarted after the change. Check the below link,
