  • 1.  After changing SEPM database to SQL ,clients show green dot one second and become offline

    Posted Jan 22, 2012 10:28 AM

    Hi

    I changed SEPM database to SQL.

    Server name ,port and IP are the same.

    I restored database backup and server private key too.

    After Updating Policy in clients they show Green dot and they become Offline.

    and clients doesn't show green dot more.

    can you please help me about root cause of the problem?

    thanks

    Despite it seems you did the right things, this a common symptom of a wrong communication certificate.

    Please, export the current sylink.xml from the manager and import it on a client, if it works, my theory is correct.

    If the suggestoin from above will not help, you can create and post here the communication log from the client. It will be helpfull for the communication troubleshooting:

    Hi

    Do you think that restoring Server Private Key and restarting the server will solve my problem?

    Hi,

    I would suggest to isolate issue first.

    Replace Sylink.xml file on 2-3 machines & check green dot stay connected or not ?

    If yes & if it's possible try to replace sylink.xml file on all the clients.

    If not, collect sylink monitor log from two worksations.

    One moe thing, have you run management server configuration wizard after doing all these changes ?

    Hello,

    Could you let us know the OS installed on the SEPM server?

    Is the SEPM sync with Active Directory?

    This issue occurs when a Symantec Endpoint Protection (SEP) client is registered in the Symantec Endpoint Protection Manager (SEPM) with a Group ID for a Group that no longer exists. This happens most frequently in environments using Active Directory Synchronization.

    Could you try replacing the Sylink.xml files on these computers and check if that resolves?

    Hope that helps!!
