Shared Session error

[Mike]

I have a shared session that uses the peer to peer capabilities of OneNote.
This session seems to work ok for a short period of about a minute then the
participant is suddenly disconnected and receives the following error: The
shared connection ended unexpectedly. We are using the "Automatically select
the port" setting. How do I go about troubleshooting this problem? Niether
party in the session appears to be loosing network connectivity when this
happens.

Thanks
Mike
