Getting "Permission Denied" error even though $.ajax call is on same domain

Getting "Permission Denied" error even though $.ajax call is on same domain

All I'm doing right here is calling a Perl script on an intranet server and using the xml results to popluate a <select> element. This works on my machine but a co-worker is getting a "Permission Denied" error when this function is executing onReady
  
function populateGroups(){  var p =1;  var groupNames = new Array();  $.ajax({          type: "GET",      url: "http://okcmonprd103/iMon/findgroups.pl",      dataType: "text/xml",      success: function parseGroupNames(xml){                $(xml).find('group').each(function(){                      groupNames[p] = $(this).find('name').text();                      p++;              });              groupNames.sort(arraySort);              for(p=0;p<groupNames.length-1;p++){                  $('#Groups').append('<option value="'+p+1+'">'+groupNames[p]+'</option>');                  $('#dutyGroups').append('<option value="'+p+'">'+groupNames[p]+'</option>');                  }      }  }); 

}

I had him run a tracert to that server and we all connected through the same network devices... And this works on a couple of other co-worker's computers. He also does have access to that server so that he can type in the url and get the xml results...

        Any suggestions?
