For Connection Server instances, security servers, and View desktops, you can enable RC4 on a Connection
Server, security server, or a Horizon Agent machine by editing the conguration le C:\Program
Files\VMware\VMware View\Server\jre\lib\security\java.security. At the end of the le is a multi-line
entry called jdk.tls.legacyAlgorithms. Remove RC4_128 and the comma that follows it from this entry and
restart the Connection Server, security server, or the Horizon Agent machine, as the case may be.
For View Composer and View Agent Direct-Connection (VADC) machines, you can enable RC4 by adding
the following to the list of ciphers when you follow the procedure "Disable Weak Ciphers in SSL/TLS for
View Composer and Horizon Agent Machines" in the View Installation document.
TLS_RSA_WITH_RC4_128_SHA
TLS 1.0
In Horizon 7, TLS 1.0 is disabled by default.

enable TLS 1.0, see the sections "Enable TLSv1 on vCenter Connections from Connection Server" and
"Enable TLSv1 on vCenter and ESXi Connections from View Composer" in the View Upgrades document.
