When we use system manager on our exchange 2003 server and attempt to expand the public or system folders, we get this error message:
An existing connection was forcibly closed by the remote host.
ID no. C0072746
Exchange system manager
We recently brought this new exchange server online and began the prococess of moving all of the mail boxes to the new server from the old exchange server. All public folders and mailboxes moved over without issue. We also followed the procedures to remove the old exchange 2003 server from the group. Our only problem is with the System manager on the new server and this error message. Other than that, it seems to be working fine.
We had SSL loaded on the IIS server, but have since removed it as part of the trouble shooting of this issue.
We have a Blackberry server with Exchange System Manager on it and the BB server can view the Public folders without issue.
We have left the old exchange server online while we finish trouble shooting this.
