Article #25815: InterClient error: "Incompatible remote protocol version"

Problem:
I'm trying to access Interbase 5.0.0.627 via Interclient 1.5.1, I have InterServer 1.5.1 
installed on this server and using InterClient 1.5.1  from the applet client.

The error is:  "Incompatible remote protocol version [15102]"

Obviously a version conflict... What do I need to resolve this  error?

Solution:
An "Incompatible remote protocol version" error occurs when the remote protocol 
version of InterClient and InterServer differ (IC and IS don't necessarily have to be 
the same version, but they must share the same remote protocol version).

There was a remote protocol version change between v1.50 and v1.51, so I suspect
you must be picking up some old 1.50 InterClient class files off disk somehow. You
can use interbase.interclient.utils.CommDiag as an applet or an application to display
the versioning info for InterClient and InterServer. 

Note: The IC class files you're picking up can vary depending on whether you invoke
CommDiag as an applet or an application.
