'rmic' assigns a serial number to the class file when it compiles it.
When an RMI connection is made, the serial numbers for the local and
remote classes are compared.  If they're different (because the two
class files are slightly different) RMI prints an error message like
the one above.

I'd guess that if you copy all the class files from the first
machine to the second one, this problem will disappear.

This happens because you're definitely using the same versions of
class files.
