"The route is not available."

This is an IP routing error usually.

If you have installed any new pieces of software that affect routing/tcpip in anyway, doublecheck their documentation as their purpose and affects.

Sometimes in some operating systems, once you make a tcp/ip change, you need to reboot the comptuer for the settings to take effect. Reboot and try it again.

Check tcp/ip in the control panel, and make sure you only have one instance of tcp/ip for each component (1 for the dialer/modem, and 1 for each ethernet card that you have), if you have extras doublecheck what they are for, but in most instances, the duplicates can be safely removed.

Use winipcfg (for windows95/98) from the dos prompt, or ipconfig on windows 2000/2003/xp to check what network adapters are installed, and that the ip's, subnet masks and gateways are for all the installed interfaces (ethernet cards, dialup-modem adapters, and wireless ethernet cards. If there are duplicate ip's/gateways etc, you could cause issues, if you aren't using your wireless ethernet card, and its a pcmcia wireless card, remove it and see if that helps.

If this happens while at work, talk to your helpdesk/network admins.
