Thanks Chris, but maybe my post was not clear enough. I have located the Project Raster tool, and have selected my input and output projections. Because the transformation between the two requires a datum change, choosing a geographic transformation is required. The problem is that, unlike when I project a vector layer with the vector tool, no transformations are available from the drop-down box. NONE! Can anyone help?
I am experiencing the same problem using ArcGIS 10 on Windows 7. The "Project" (vector) tool works as it should, the providing option to select a desired transformation from a drop down list. The "Project Raster" tool does not. The "Geographic Transformation (optional)" parameter is unusable (no drop down list).
I've personally seen this, but it's never been reliably reproduced in-house.
Workaround:
1. Add the raster to ArcMap
2. Set the data frame's coordinate system to the target coordinate system (data frame properties, coordinate system tab)
3. Set the appropriate geographic/datum transformation (same tab, transformations button)
4. Right-click the raster layer in the table of contents and on the context menu, select data, export data.
5. In the export data tool, select the data frame's coordinate system.

Thanks for the work around. The work around is functional, but it is not ideal for mass reprojecting rasters.
Cheers,
