coordinate conversion problem

[Didrik Pinte]

Hi,

I'm using a lot of rasters and one shape file in Esri
NTF_France_Lambert_II coordinates

I've translated NTF_France_Lambert_II in epsg:27572

I will have a layer of GPS points in latlong coordinates. To simulate
this, I took a shapefile in Esri NTF_France_Lambert_II coordinates and
convert it using ArcGIS to GCS_WGS_84.

I've translated GCS_WGS_84 to epsg:4326

When I look at the map, my latlong points are nearly 400 km on the left
of the original points ...

How can I solve the problem ? Did I choosed a bad epsg reference ? 

Thank you in advance for your help

Didrik
