A minimum recommended configuration for a VTS/IS is:
• Installation of VTS
• Windows (XP or Vista. A server class operating system is recommended for production systems.)
• Access across a network to workstations which have Internet Explorer 6.0 or later installed.
• In the event that the clients connect to the VTS/IS via proxy servers (common where a firewall is employed), it is advisable that the proxy servers support the HTTP 1.1 protocol, rather than only HTTP 1.0. (See: Enable HTTP 1.1 in Microsoft Internet Explorer).
• The server name should contain only letters, numbers and hyphens (as defined in Section 3.5 of RFC 1034 and Section 2.1 of RFC 1123 of the Internet Engineering Task Force). Characters such as underscores are not recognized by this standard and may cause unexpected behavior.
