This issue has been solved. See solution.


I have a question about a failover cluster im using for RDS, when i install SEP 12.1.4 on the servers the cluster fails.


I believe in the release notes Symantec mentioned that this issue was fixed?
Im running the "full server protection"package on these servers.

Have you followed this?

Installing a Symantec Endpoint Protection (SEP) client to a cluster server

If you are instaling NTP I would first put all the rules in Test mode, Log only.

Hello Levd,

Rafeeq is right. As you well know network connection is very important for cluster systems. Please check network connectivity after install sep, and you should open cluster ports;

UDP 3343

TCP 3343 (required)

TCP 135

UDP 137
