We use IM on several different networks plus across different domains
with no problems, it's ether DNS or it's a security problem.

        Dear exclist;
          About the instant messaging in exchange server2000, i have 2
server with 2
          diferent network, first server is A class and the second is B
class and
        the
          communication is ok. and there is instant messaging in A
class.
          But when all user in A class use msn exchange messenger
service to send
          message the other user to the same network in A class, there
is no
        problem.
          but if user in A class send message to user in B class (over
the other
          domain), there's a problem (the message cannot deliver), but
if user in B
          class send message to A class, it's ok.
        
          and so i check it up to website log, and all ip client in B
class notes
         ip_server(in B class), not detect own ip client (ip client in B
class).
        
          Please help me, what should i do to fix it up?
          I need your all suggest...
        
          Regards;
          Amos
