Niagara SCX User Guide
ViewCast 15
NOTE: You now completely installed the Niagara SCX and SCX Explorer applications.
You must install the SCX version on the Niagara streaming server or your
customized server. You then may optionally load Niagara SCX Explorer on your
remote workstations (laptops and computers) and use it remotely from the Niagara
streaming server or your office.
IMPORTANT! You must restart your computer before you begin to use SCX.
Use Windows Update to check for any critical updates to the Microsoft .NET
Framework. This crucial step allows SCX and SCX Explorer to run properly. The
Microsoft .NET Framework, an infrastructure library, provides the foundation
required for Niagara SCX and Niagara SCX Explorer to operate effectively.
Configure Niagara SCX for Firewall and
DCOM
You must take the next step to configure the application – Niagara SCX – after installing Niagara
SCX and Niagara SCX Explorer (for remote installations).
To do this, you must set the firewall and DCOM configurations first.
The Microsoft Windows XP Service Pack 2 protects the machine from attacks over the network.
These changes also prevent the SCX clients from communicating with the servers. The following
sections outline the steps required to allow this communication.
The two-part changes involve both the server and client. To implement the changes to the server,
open the DCOM to the previous level of authentication. For the clients, Microsoft Windows XP
notifies users when ViewCast applications try to access the network. The user simply needs to select
Unblock to allow the request to complete. Once they do this, users do not receive this request again
for that application.

SCX Explorer run Microsoft Windows XP with Service Pack 2.

Start ¾ Control Panel ¾ Administrative Tools in Classic View.
