I have the same problem, on my primary computer (Windows XP Pro , but the cause may be different from what 123polis123 had.

It seems that the installer installed the Enterprise Multiserver configuration instead of the built in server.

Note that I installed sucessfully on my laptop (Windows XP Home), using the same install parameters.

I chose the "Server configuration" which has a self contained server tunning a single instance with an embedded JEE server.  After running though all the installation screens, before proceeding with the actual installation, the installer reported the following:

Installation Type:

  Server configuration

Licensing:

  Developer Edition

Installation Directories:

  Product: C:\ColdFusion9

  Web root: C:\ColdFusion9\wwwroot

Server Information:

  Web Server: Built-in web server

  Port: 8500

  ODBC Services: installed

  Search Services: installed

  ColdFusion Solr Search Services: installed

  Microsoft .Net version: v 2.0.50727

  .NET Java Port: 6085

  .NET Client Port: 6086

  Documentation: installed

  RDS: enabled

Disk Space Information (for Installation Target):

  Required: 1,089,069,939

  Available: 7,387,262,976

The installation proceeded without a hitch, except at the end when the browser is supposed to come up with the admin configuration page it can't find the server.  Port 8500 is open. I fiddled around awhile to see what the problem was.  I installed on the other computer which went fine - the only difference is that the .NET version is 1.1.4322.   I then re-installed, without uninstalling, on the problem computer.  When the installer got to the screen where I select the server configuration, Enterprise Multiserver configuration was selected and it was not possible to select onything else.   I uninstalled and re-installed.  Same thing happened.

The processes running included: k2admin.exe, k2index.exe, k2server.exe and CFDotNetsvc.exe.   The processes on the sucessful install included cfp.exe and cfupdate.exe.

Note that I had installed Eclipse and the CFEclipse plugin before installing CF9.

There could be any number of reasons why this is. It will be helpful for you, in the long term, to learn some basic diagnostics.

Is the service running?

Have you checked the service logs?

If you check for listening ports, is 8500 in use?

If the service fails to start properly, can you start it as an application?
