When I try to connect online help documentation, it tries some local host location as follows:
The requested URL could not be retrieved


While trying to retrieve the URL:

The following error was encountered:

Access Denied.
Access control configuration prevents your request from being allowed at this time. Please contact your service provider if you feel this is incorrect.
I tried Window->Peferences->General->Web Browser and tried to set external web browser as mozilla and IE, but did not help. It does not even bring the browser after configuring this.

I also tried Window->Peferences->Help Server. But I must know the hostname or IP address and port to connect there. So can anybody tell me what is worng with this or what is the hostname and port to connect help server???
