HTTP server does not work

Question

I cannot start my HTTP server. If I go to options>IDE configuration>Server and External Tool settings>HTTP server I cannot select truefrom the drop down menu and start the server. I get an error saying "Unable to start the HTTP server please check that the port is not in use." I then try to change the port number but it gives me the same error and resets the port number to something else.
This is a big problem because I cannot start my Tomcat, and I cannot even test my applets, because this error message always pops up. The command window sais: "
Connection Refused" when I try to test my applets.
Thank you very much for your time and help

Hi Sanjeev,
thanks for your response. I am using Windows XP. The error message that I am talking about pops up on everything. When I try to start Tomcat it pops up. I cannot even test my applets because the error message pops up. (The error message pops up several times and I have to close it). Actually after I close the the anoying error messages an Internet Explorer window appears and my applet is running. The same thing is with Tomcat. It works only after I close the error message which pops up several times.
Here is what happens in the command window when I run an applet:
Tomcat Internal

(there are 3 GET becace the error message poped up 3 times).
I have also tried to change the port and the same thing as you said happens. It changes to a different one, but I still get the error message.
