3-20 INSTALLING TELEVANTAGE
TeleVantage Web Services requirements _____________________
You can install TeleVantage Web Services on the same PC as the TeleVantage Server if you
plan to use the IIS to support a small number of simultaneous connections for TeleVantage
purposes only. However, if you plan to use the TeleVantage Web Services to support many
TeleVantage users or for other high-volume Web-related activity, it is recommended that you
install it on a separate networked PC from the TeleVantage Server.
Important:
Be aware that installing IIS on the TeleVantage Server is a potential security risk.
Installing TeleVantage Web Services and IIS on a separate server limits the impact of a security
incident.
The PC on which you install TeleVantage Web Services must meet the following minimum
requirements:
Q Operating system. The following operating systems support more than 10
simultaneous users:
Q Windows Server 2003, base release as well as SP1 and SP2
Q Windows 2000 Server, SP4 or higher
Q Windows NT Server 4.0, SP6a or higher
The following operating systems support up to 10 users connected to the Web server
simultaneously:
Q Windows 2000, SP4 or higher
Q Windows XP Professional or Windows XP Home, base release as well as SP1 and
SP2
Q Windows NT Workstation 4.0, SP6a or higher.
This operating system requires Microsoft Internet Information Server (IIS) 4.0 or
greater. IIS 4.0 is part of the Windows NT 4.0 Option Pack.
Note:
If your TeleVantage Web Services PCs currently run or will run Windows XP
Professional SP2 or Windows Server 2003 SP1 or R2, review the important information
about Windows Firewalls in Appendix F, “Configuring TeleVantage for the Windows
Firewall.”
Q Processor. Minimum Pentium II 400 MHz.
Q Memory. 256 MB, plus ~ 15MB per simultaneous Viewpoint Web Access user. For
example, if your office of 100 users expects 20 simultaneous Viewpoint Web Access
connections, your Web Services PC should have 256 + (20 * ~15) = ~ 556MB of
memory.
