An existing connection was forcibly closed by the remote host. Facility: Win32 Id no: c0072746 Exchange System Manager.
I haven't been able to dig much up on this error. Was this server ever a Small Business Server? Are you replicating public folders? From the bits I have read, I recommend you call Microsoft Product Support Services (PSS) about this one. Hope that helps.

I had this exact same error message, and reapplying Windows Server 2003 SP1 fixed the issue. Go figure.
I hope this helps.
