Introduction

When connecting computers loaded with Microsoft Windows operating systems to devices on Ethernet, it is sometimes difficult to establish a connection. This document gives some suggestions on where to go within Windows operating system to try and solve these issues.

Design Considerations

The solutions offered below to Ethernet connection issues assume that the physical side of making the connection is working correctly. One of the most common setup issues in Windows is security settings. Typically these come in the form of installed software components against individual network connections or firewalls.

Installed Software Components: For installed software components it is worth looking at what is configured for each connection and possibly turning some things off.

Windows XP Example:

From the Windows menu, select Settings and then Network Connections.

At this point, right-click on the connection required and select Properties. In this example we can see an item called “Check Point SecuRemote”. This may cause connection problems so it should be un-ticked followed by selecting OK to save the change.

Firewalls: firewalls and firewall settings can be a little more complicated as it depends on what firewall has been installed and what settings have been configured within it.

The standard Windows firewall can be found within the Windows Control Panel. One obvious solution to firewall blocking problems is to temporarily turn the firewall off, but this may not be a viable solution because it can expose the computer to virus attack from the internet if connected to the internet.
