Hi DCOMP,

Symantec AntiVirus 10.x (SAV 10) and Symantec Endpoint Protection (SEP) are two different products.  A SAV client on a serevr cannot update from a SEPM.

Hope this helps!

Hi,

If you are talking about SEP try to replace new Sylink.xml file on affected system.

Sylink locations

SEP 11.x --> C: OR installed drive \program files\Symantec\ Symantec Endpoint Protection

SEP 12.1 --> C: OR installed drive\Documents and Settings\All Users\Application Data\Symantec\Symantec Endpoint Protection\12.1.1000.157.105\Data\Config

After replacing Sylink if communication did not restore, run Sylink monitor tool on affected system.

Attach those Sylink logs to this thread.

Already I replaced the sylink.xml, but stil the problem is same.,

Hi,

You can try shared article by Techies , also attach Sylink logs from affected system.

Run Sylink monitor tool at least 10-15 minutes.
