The server name or address could not be resolved

HI there

Everytime I go to click on RDS login in the Application window I get a message
stating:

The server name or address could not be resolved.

Possible reasons:

1. The URL specified for this site's testing server maybe incorrect:
http://localhost/mysite/
2. The testing server maybe incorrectly configured (e.g. ColdFusion may not be
running).

I have check and CF is defintiely running

I'm lost and dont know why this error is coming up, and how to resolve the
issue.


I'm using Freamweaver CS3

The following solved this issue for me with Dreamweaver CS3 and CF 8: 1)
created the folder main in CFIDE directory in website root
(c:\inetpub\wwwroot\CFIDE). 2) in this main directory, created empty text file
named ide.cfm. 3) Restarted Dreamweaver and clicked on RDS login, it asked me
for username and password.

This CFIDE\main\ide.cfm file is listed in the
C:\ColdFusion8\wwwroot\WEB-INF\web.xml file in one of the two RDS entries here.
