i installed wamp in my local server system.It worked fine .But i am getting some problems in that.

After installed the wamp server i changed the port number as 81 because my IIS port number is 80.

When i give the url as http://localhost:81/ it worked fine and opened the wamp server index page.

In localhost place i replaced the my server ip address as
it shows the error message
You don't have permission to access / on this server.".

Any body could you please tell the solution how can i resolve the problem.

Thanks .
