MSIR.0903 (protocol) protocol error
A Janus connection using the indicated protocol encountered invalid data according to that protocol. The most common cause of the problem is a connection between a client and server using different protocols — for example, a connection from a web client to a telnet server or from a SMTP client to a web server.
If this is believed not to be the case, contact Sirius Software technical support. To facilitate diagnosis of this problem, it is useful to reproduce the problem with a TCP trace — TRACE set to 8 either on the JANUS DEFINE for the port or via the JANUS TRACE command.
