3.2.4 Network Evolution Issues
This document is as correct as possible at the time or writing. However, network management is an
evolving discipline, and conditions will change. Some of the drivers for change include network
security, authentication, and data integrity. Technology changes factor into all of these issues.
Because the network communication environment is complex and ever-changing, we have tried to
provide the basic information needed for connection of the XDS instrument. 95% of users will have
no connection problems, if these instructions are followed.
In the rest of the cases, there may be network issues, corporate restrictions, or other issues which
inhibit easy connection. The troubleshooting section covers some of the most common problems.
In all cases, we recommend minimal tampering with computer settings. This can cause instability, and
may be prohibited by company policies.
At this time, we recommend Microsoft Windows® XP as the easiest operating system by which to
establish network communication. We strongly recommend that Windows 95, 98, and NT 4.0 be
avoided, as they require considerable expertise in network configuration.
