Copying WordPress to a new server

Hello All,

I am running WordPress Bitnami Stack on Windows.

For testing and dev purposes I am copying my entire WP installation to another server using these instructions from the Bitnami site;
On Windows:
On Windows, you should follow the same process. Stop the servers using the shortcuts and copy the whole installation directory. To restore the system, copy the directory to a different Windows machine in the same location and follow these steps from a command prompt:
$ cd installdir
$ serviceinstall.bat INSTALL
You can access your BitNami Application at the usual URL.

I run this but when I visit the site page I get the error; Error establishing a data connection

Any thoughts?
