Can't get xammp working

[t2010]

If i type http://localhost/phpmyadmin or http://localhost/myfolder, i get the following error
message from the browser:
Connection Interrupted
The document contains no data
The network link was interrupted while negotiating a connection.Please try again.

The xampp control panel is running in the background.

How do rectify this.

Three quick questions:

Is is ONLY those two folders you can't access? For instance, does the default XAMPP page appear when you go to http://localhost ?

Have you tried more than one browser?

Is MySQL running in the control panel?

It may possibly be your firewall or ZoneAlarm etc. that is blocking ports 80 - 443 - 3306 and any other port that XAMPP uses.

You will find a list of port numbers here:
The following ports are used for basic functionality (link)

Have your firewall exempt these ports if that is the case.

Also make sure your browser is not set to Work Offline.
