Well, I solved the problem addind "S" IP to the "Trusted sites" list:
http://windowsxp.mvps.org/networkfile.htm
I don't really know why it's working. When P1 and P2 were opening a97.mdb,
they was getting a warning message, not P3. We've got use of it. Probably
this security check was causing some kind of error when trying to open an
already opened db.
Thanks to those who replied.
