This now sounds more like a OpenLayers question and you should be asking
in that list. My OL file look like this and they work:
var map;
var epsg4326 = new OpenLayers.Projection("EPSG:4326");
var epsg900913 = new OpenLayers.Projection("EPSG:900913");
function init(){
map = new OpenLayers.Map('map', {
maxResolution: 156543.0339/2,
numZoomLevels: 18,
units: 'm',
maxExtent: new OpenLayers.Bounds(-20037508.34,
-20037508.34, 20037508.34, 20037508.34),
sphericalMercator: true,
projection: epsg900913,
displayProjection: epsg4326,
controls:[
new OpenLayers.Control.LayerSwitcher(),
// new OpenLayers.Control.OverviewMap(),
new OpenLayers.Control.Permalink('permalink'),
new OpenLayers.Control.MouseToolbar(),
new OpenLayers.Control.MousePosition(),
new OpenLayers.Control.PanZoomBar(),
new OpenLayers.Control.Scale(),
new OpenLayers.Control.ScaleLine()
]
});
var wms = new OpenLayers.Layer.WMS(
"Guatemala WMS",
"http://imaptools.com:8080/cgi-bin/mapserv?";,
{ map: "/u/data/maps/somemapfile.map",
format: "image/png",
layers: "MapFileName"
},
{
sphericalMercator: true,
transitionEffect: 'resize',
singleTile: true,
ratio: 1.0
});
wms.addOptions({isBaseLayer: true});
wms.setVisibility(false);
...

After I set the projection of the map as epsg:900913, on client-side,
Openlayers still tells me that the projection of this layer is "EPSG:4326".

Js code:
var propertydata_layer = new OpenLayers.Layer.WMS(
'Property Data',
'http://localhost:9999/cgi-bin/mapserv.exe?map=c:/ms4w/Apache/htdocs/global.map&;',

this.map.addLayers([propertydata_layer]);

Is this a Mapserver issue or Openlayers?
