System information

Host Installation
 Minimum requirements – Same as those specified by Microsoft for the respective
operating system.
 Recommended requirements – Same as those specified by Microsoft for the
respective operating system.
Installation requirements
The following additional requirements are required or recommended for installation of
PC-Duo Host:
 Windows Installer 2.0 or later – Required by the installer. If needed, this upgrade is
applied automatically when the setup.exe installer image is run.
 Acrobat Reader – Required for documentation.
 Local Administrator access rights – PC-Duo Host runs as a Windows service on the
local machine. Therefore, Local Administrator access rights are required for the user who
is installing PC-Duo Host on the machine.
NOTE: These prerequisites are met by the supported platforms, and therefore they are
not included in the PC-Duo software distribution packages.
Network requirements
PC-Duo Host operates over any type of network, including dial-up, Ethernet, token ring,
and FDDI, provided that the network supports the TCP/IP, UDP/IP, IPX or SSL protocols.
The following conditions apply:
 IP is a general-purpose protocol supported on a wide variety of networks and servers.
To enable communication using TCP or UDP over IP, you must enable the Microsoft
TCP/IP Protocol (or you can use another WinSock 2 compliant IP stack).
 IPX provides access to Novell NetWare servers. To enable communication using IPX,
it is not necessary for any computer to be logged into a NetWare server, nor is it
necessary to run a NetWare client. To enable communication using IPX, you must have
the Microsoft NWLink IPX/SPX Compatible Transport (included with the operating
system).
 The SSL protocol runs above TCP/IP and below higher-level protocols such as HTTP
or IMAP. Using TCP/IP on behalf of the higher-level protocols allows an SSL-enabled
server to authenticate itself to an SSL-enabled client, and both machines to establish an
encrypted connection.
 The PC-Duo UDP, TCP and SSL transports fully support IPv4 and IPv6 addressing.
