Network Admin pointing to the wrong URL

Hello. I actually tired this based on another forum entry. After making this change I get an error in my browser telling me “Error establishing a database connection”

I have confirmed that ALL plugins are disabled and have tried activating the 2010 theme. Still no luck. When I need to use the Network admin portion of the WP installation for testing of this problem, I simply manually edit the URL. Just an FYI.

                    <action type="Rewrite" url="C:/WordPress/{R:2}" />
                </rule>
                <rule name="WordPress Rule 6" stopProcessing="true">

                    <action type="Rewrite" url="index.php" />
                </rule>
            </rules>
        </rewrite>
    </system.webServer>
</configuration>

I also just noticed something. On the banner next the the WP logo there is the My Sites pull down which exposes the Network Admin and the Lawnside site. The URLs for My Sites and the Lawnside site are correct. It is ONLY the Network Admin URL that is incorrect.

Well after MUCH searching I found a way to fix the situation. However, it does break the golden rule – NEVER HACK the CORE. With that said let me explain the fix. The file called linl-template.php in c:\wordpress\wp-includes\ The original code is as follows:

function network_admin_url( $path = '', $scheme = 'admin' ) {
	if ( ! is_multisite() )
		return admin_url( $path, $scheme );

	$url = network_site_url('wp-admin/network/', $scheme);

	if ( $path && is_string( $path ) )
		$url .= ltrim($path, '/');

	return apply_filters('network_admin_url', $url, $path);
}

If I make the following change

$url = network_site_url('wordpress/wp-admin/network/', $scheme);

Everything works!! The problem is that this is not the best approach. The better approach is to modify PATH_CURRENT_SITE in wp-config.php in \wordpress directory but when that happens I get an error telling me that a database connection cannot be established.

Has anyone been able to solve this situation….???
