SEP client 12.1.2015.2015 communication troubleshooting problem

Created: 28 Dec 2012 | 17 comments

Hi all, happy New Year !

I had a problem with some client workstations.

In order  :

- install the client from the management server for a specific group.

- checking successful installation on the client system logs

- after installation make client workstation reboot

- client icon not displayed in SEP management console.

- I log on as administrator on client  workstation, start SEP client GUI, open tab Troubleshooting and see, that the client included in another group.

- but in SEP management console client icon not displaed in another group

- search client in SEP management database does not find

- I take SyLinkDrop and correct sylink.xml file. SyLynkDrop report - file replaced. But Troubleshooting tab displaed wrong group.

- I export policy and import on client. After import policy Trobleshoting tab display correct group and policy number and quickly return wrong group and policy number.

This sequence is independent of the operating system and it was fresh client installation or upgrade from version 11.0.6000.645

Any ideas...

Try to only one or two client.

Exporet ne package and check

Create custom client install settings:

  1. Log on to the SEPM you wish to have manage the client.
  2. Click the Admin tab, then click Install Packages.
  3. Click Client Install Settings, then click Add Client Install Settings.... This will open the Add Client Install Settings dialog.
  4. At the bottom of the page under Upgrade Settings: select the setting Remove all previous logs and policies, and reset the client-server communications settings.
  5. Set all other options as desired.
  6. Click OK.

Export new sep client package as per artical

Is there a Replication set?

Currently, What version is the SEPM and that client running on?

In your case, check this Article:

Symantec Endpoint Protection clients can no longer communicate with Symantec Endpoint Protection Manager after Symantec Endpoint Protection Manager was upgraded from SEP 11 to SEP 12.1

Did you work as per the Best Practices of Migration- 

Best practices for upgrading to Symantec Endpoint Protection 12.1.2

Hope that helps!!
