created grids from geostatistical analyst layers that only seems to load correctly on my PC. When others add the grid to a project (mxd) file, the grids are shifted to the east and slightly north.

I'd start by checking the Coordinate Reference System of the Grids and then also in the ArcMap Data Frames for all the parties.  What likely is going on is that the grids are not in a Coordinate Reference System, but either you or your colleagues are using a Coordinate Reference System in the MXD, so what you are seeing is the result.

If it is a "small" shift, it might be as simple as a difference in Datum's.  For example, here in California a difference of about 200 feet in a NorthEast-Southwest direction is often a giveaway of a NAD1983 vs. NAD1927 Datum Shift.  In this case, one data layer may have been assigned to NAD1927 when it should have actually been assigned to NAD1983, or vice versa.

Thanks for the reply Chris. The geostat layer and the grids are in state plane washington north (FIPS 4601), nad 83. We have had some luck with reprojecting the layers but then they don't plot correctly with our basemap, which is in  Web Mercator Auxillary Sphere. seems to me that something went awry when I converted the geostat layer to a grid.
