IBM Lotus Sametime 7.5.1 Release Notes
Community Services on port 80.
z A Sametime Meeting Room client can make HTTP-tunneled connections to both the
Sametime Community Services and Meeting Services on port 80.
All of these connections can occur to the same DNS name using port 80. On a Sametime 7.5.x server, it
is not necessary to assign separate IP addresses to the HTTP Services, Community Services, and
Meeting Services to enable connections to all services to occur using a single DNS name on port 80. The
design of the Community Services multiplexer on a Sametime 7.5.x server makes this capability possible.
The Community Services multiplexer can listen for HTTP connections from Web browsers, Sametime
Connect clients, and Sametime Meeting Room clients on port 80. The Community Services multiplexer
examines these connections and then forwards the connections to the appropriate service. For example,
the Community Services multiplexer forwards the Web browser connections to the Domino HTTP Server,
the Community Services connections to the Community Services, and the Meeting Services connections
to the Meeting Services.
Note that the Community Services multiplexer on a Sametime 7.5.x server cannot listen for connections
on port 443 or 563 and then forward these connections to the Domino HTTP server. The Community
Services multiplexer can forward HTTP connections on port 80 to the Domino HTTP server, but not
connections on port 443 or 563. For this reason, a Sametime 7.5.x server must be assigned multiple IP
addresses when both the Domino HTTP server and the Sametime Community Services on the Sametime
server must listen for connections on port 443 or 563. The Community Services multiplexer on a
Sametime 7.5.x server also cannot listen for HTTPS connections to the Sametime Meeting Services or
Community Services on ports 443 or 563 and forward these connections to the Community Services and
Meeting Services. HTTPS-tunneling to the Sametime Meeting Services is not supported. Sametime
Meeting Room clients cannot connect to the Sametime Meeting Services through an HTTPS proxy server.

Windows DEP process causes launch error
If Windows server administrators are running the Data Execution Prevention (DEP) process on their
Windows server, the server will view the Sametime launch task StLaunch as a potentially malicious
thread, and halt the process. The error message received is:
To Help protect your computer, Windows has closed this program:Name:
StLaunchPublisher:
Workaround
Turn off the DEP process on Windows servers before launching the StLaunch task.
