We have 1 old RDS server and just setup 2 new RDS server, both of them installed Connection Broker, Session host, licensing and Web access role.
After setup and install the RDS license in 2 new servers. We found there are some 135 port traffic to the old RDS server occur on each hour.
What is this traffic and how to stop it?
new RDS1 and RDS2 > old RDS have 135 traffic
old RDS > new RDS1 and RDS2 no 135 traffic
new RDS1 > new RDS2 no 135 traffic
