RDS Login Fails - using Tutorial

Using the ColdFusion 8 getting started tutorial (Steps_for_building_dynamic_pages_en.pdf), at the point in Dreamweaver 8 you set up the database and click on "RDS Login" (page 18) , rather than letting you login to the server, you get the error message:
____________________________________________________________

The server name or address could not be resolved

Possible reasons:

1. The url specified for this site's testing server may be incorrect: http://localhost:8500/cf8gettingstarted/tutorial/
2 The testing server may be incorrectly configured(for example, CF may not be running)
____________________________________________________________

Doing a Google search shows other users with the same problem (but no solution). The testing server address shown in the error message is the correct one and is the one specified in the tutorial. I've confirmed CF is running by creating and putting the "testtime.cfm" file into the test directory and running it from the browser. I've also disabled the Firewall (although it shouldn't be an issue).

Any ideas?

It doesn't give you much comfort that the ColdFusion 8 Demo doesn't work. With other obvious errors in the demo, I may be the first one to have actually run it (some screen shots don't match the written instructions).

Defender has nothing to do with AV, that would be Microsoft OneCare.

Defender is more of an intrusion prevention service and it will allow or disallow programs to run and or communicate if it deems necessary.

In the software browser section it will show a list of programs. it shows all the startup programs by default, but you can switch the view ti "running programs" and see those ones (make sure DreamWeaver is running first).

look for DreamWeaver and see if it says "allowed", "disallowed", or "pending"

It likely isn't Defender if the firewalls were not catching it, but it is just another thing to check.

I run Vista Ultimate as well, but I have my dev servers on the network on totally different boxes (and OS's) from the computer I actually program on. RDS via CF Studio works fine in that situation, connecting to a remote server - I do not use DreamWeaver.

Since I do not run the server locally nor use DreamWeaver, I don't really have the tools in place to experiment much further on your type of situation, but so long as you are running Ultimate, all the communication protocols should be available by default, so that won't be the problem.

Sorry I can't give you much more insight on this under your setup.

RDS communication protocol would be part of Vista.

Check the Windows firewall settings and see if it is blocking DreamWeaver form communicating, or alternatively specifically tell it to allow DreamWeaver to communicate.

All network communications run through the Windows firewall regardless of whether or not they are local.

I am trying to find the information about RDS communication on Vista, but as usual, MS's help files leave a lot to be desired. Telling the firewall to specifically allow DreamWeaver communication may trigger the requirement though.

Also, check defender (on Vista by default) - it could also be disallowing communication with DreamWeaver. You can look in the software browser section and check for DreamWeaver in the "currently running" section to see what status it has.

What flavour of Vista are you running?

Thanks for helping with this - I'd really like to fully evaluate CF8, as we have a large project starting that will likely be perfect for using CF8.

I have Windows Firewall off, and use SystemSuite's firewall. Even disabling all firewalls temporally (something I don't like to do), it still fails. I've also looked at the Firewall logs and there are no items attempting access that are being blocked.

I think Windows Defender is more of a poor-man's anti-virus, but I don't see any way to actually turn it off. It does not indicate anything is quarantined (I also use Trend's AV via SystemSuite).

The system is using Vista Ultimate 32-bit, 4 GB RAM (really 3.2 usable), Intel Duo Core, etc. System is less than 2 months old, and has been quite stable.

Try replacing "localhost" with 127.0.0.1 or even the actual IP of your machine as supplied by the router or your ISP ( depending on how it obtains IP)

While localhost is a common default alias, sometimes it is not mapped properly ( or at all) on machines. I have never been able to use "localhost" on many machines, but the 127 address and the actual address of the machine always work.

The port address should be OK if you are running the included server and you can access it via web on that port.

If you are on Vista, make sure that RDS communications are turned on. Since it is not an actual server machine, it most likely does not have that capability turned on by default. If it is Vista Basic or Vista Home, networking protocols and abilities are not included, which could also be a problem.

If the server is running on the local machine anyway, you really do not require RDS to connect and edit etc, you just need to browse to the local server directory and edit that way. RDS is usually reserved as an option for connecting to a remote server.

If the server in question is a remote server, then that is your problem, since "localhost", "127.0.0.1", etc are all alias's for your own system, not the remote system.

I don't think the localhost is the issue, but I tried changing to 127.0.0.1, but the same problem occurs. Both localhost and 127.0.0.1 do work with a timetest.cfm program:
http://localhost:8500/cf8gettingstarted/tutorial/timetest.cfm
Which confirms the CF8 server is working locally and running.

As for RDS communications, is this part of Vista or CF8? I don't see a Vista service for this function in the services list, nor any thing in Google on how to turn this on in Vista. Looking at CF8 Admin, I do have "Enable authentication for RDS access" set to yes, and "Allow access through RDS with Single password" also set to yes.

It sounds like RDS is not really necessary for a local server? I'll try to continue the tutorial without it and see if it works.

Further update: You can't go further without going through the RDS step. Any other ideas?

Hi,

Which Webserver are you using there?. IIS or the Built in Wevserver that comes along with CF?

IIS is not installed. I'm using the built in CF8 Web server on the local machine. Services running include CF8 Search Server, CF8 ODBC Server, CF8 ODBC Agent, CF8 Application Server, CF8 .NET service. System is a high-end Vista system if it matters.
