Socket error while trying to save imported broker file

Hi all,

We are encountering a strange problem while importing a broker and saving it. We are using a windows 2000 server with sp4 and have gone through the installation procedure several times. The installation goes smoothly. After installation we open the Enterprise manager and create a new broker. Then we open the enterprise integrator and import an adl file. There is no error till this point. Its when we try to save the session, that we encounter the following exception: "Unable to send to broker: Error ‘ SocketException’: Connection reset by peer: socket write error’ was reported by the send call.

Please suggest.
