Currently, the dde module only supports a single server.
If you're running your script from Pythonwin, one server has
already been created, but you can use the /nodde switch to
disable Pythonwin's builtin dde server.

In the past, the dde module supported multple servers, but
that has since been disabled. It was done through some
low-level hacks to create new C functions on the fly, which
set off DEP and crashed in a 64-bit build.

There are also some conceptual difficulties in how the dde
module operates, mainly that you must initiate your own
server in order to establish a conversation as a client.

It will take a major overhaul of the module to fix these
issues.  However, I think DDE is actually considered
deprecated by Microsoft so it's unlikely that anyone will
go to the trouble.
