The installtion is Openfire 3.6.4 on Windows 2003 SBS using the embeded DB. The install was working fine and all was well with the admin console.
An unrelated software upgrade required that SQL 2005 Express be installed along with some .NET framework stuff. I’m not sure if this was the cause but around that same period of time I am no longer able to login via the admin console. I’ve reinstalled Openfire, renamed the old dir and installed to a new to no avail. Clients can still connect and chat.
This is the error when trying to login via http:
.NET System.Runtime.Remoting.RemotingException: Tcp channel protocol violation: expecting preamble.
at System.Runtime.Remoting.Channels.Tcp.TcpSocketHandler.ReadVersionAndOperation(U Int16& operation)
at System.Runtime.Remoting.Channels.Tcp.TcpServerTransportSink.ServiceRequest(Obje ct state)
Uninstalling the other updates isn’t an option since they are required for our new application.
