4 Restart the VMware Blast service to make your changes take eect.
In the Windows guest operating system, the service for the HTML Access Agent is called VMware Blast.
To revert to using the default cipher list, delete the SslCiphers value and restart the VMware Blast service.
Do not simply delete the data part of the value because the HTML Access Agent will then treat all ciphers as
unacceptable, in accordance with the OpenSSL cipher list format denition.
When the HTML Access Agent starts, it writes the cipher denition in the VMware Blast service's log le.
You can discover the current default cipher list by inspecting the logs when the VMware Blast service starts
with no SslCiphers value congured in the Windows Registry.
The HTML Access Agent's default cipher denition might change from one release to the next to provide
improved security.
Configuring iOS to Use CA-Signed Certificates
To use HTML Access on iOS devices, you need to install SSL certicates that are signed by a Certicate
Authority (CA) instead of the default SSL certicates that are generated by the View Connection Server or
the HTML Access Agent.
For instructions, see "Congure Horizon Client for iOS to Trust Root and Intermediate Certicates" in the
View Installation document.
Upgrading the HTML Access Software
For most versions of HTML Access, upgrading involves simply upgrading Connection Servers and View
Agent.
When you upgrade HTML Access, make sure that the corresponding version of View Connection Server is
installed on all the instances in a replicated group.
When you upgrade Connection Server, HTML Access is automatically installed or upgraded.
N To check whether the HTML Access component is installed, you can open the Uninstall a Program
applet in the Windows operating system and look for HTML Access in the list.
Uninstall HTML Access from View Connection Server
You can remove HTML Access by using the same method you use to remove other Windows software.
Procedure
1 On the View Connection Server hosts where HTML Access is installed, open the Uninstall a Program
applet provided by the Windows Control Panel.
2 Select the program VMware Horizon 7 HTML Access and click Uninstall.
3 (Optional) In the Windows Firewall for that host, verify that TCP port 8443 no longer allows inbound
trac.
What to do next
Disallow inbound trac to TCP port 8443 on the Windows Firewall of any paired security servers. If
applicable, on third-party rewalls, change the rules to disallow inbound trac to TCP port 8443 for all
paired security servers and this View Connection Server host.
