After you install or migrate to Symantec AntiVirus 10.0.0, you see the following error message on the primary server:
"Symantec AntiVirus communications layer failed to initialize. Remote manageability has been disabled. An error occurred while initializing SSL-based communication. Error code: 0x20000081."
After this message appears, Symantec System Center cannot communicate with the primary server. If you restart the Symantec AntiVirus service on the primary server, you can restore communication temporarily.
In some cases, the error message does not appear, but Symantec System Center cannot communicate with the primary server.
