The blades are HS21, by IBM, with 2 cpus and 4 cores. We built a new windows server on a BLADE and created a database. The program did not worked.
It seems that having BLADE as client and database server cause the problem. We are currently building a new server, not blade, to see if it will work.

We also found that the Linux (non blade) machine that works has some rpm's that are not installed in the ABC machine.
