It was failing with the same ruby stack trace that Vedran had (as

could still carry on using the meterpreter perfectly.

The error code 1168 is windows system error ERROR_NOT_FOUND which seemed
 to be returned from the server side code based on my brief code analysis.

If this is definitely just due to the file size then I guess it is not
so big an issue unless people want to write some huge extensions.
However, I just figured it might be worth a little bit of investigation.

If there is anything specific you'd like me to do/test or if you'd like
me to send you an example compiled DLL that fails on win2k3 then let me

As it relates to size, my only guess would be that somehow an incomplete
version of the DLL is being sent to the server.  Here's something to

In lib/rex/post/meterpreter/client_core.rb inside load_library, there's
this block of code:

::File.open(library_path, 'rb') { |f|
   image = f.read

Try adding a $stdout.puts("#{image.length}") after that block.  Compare
the output to the size of the file.  If they mismatch, then we know this
is the problem.
