Alert configuration Not working in RWB

Hi,

In RWB alertconfiguration is not working, showing the error

<b>404 Not Found</b>". I gone through this thread

alert-configuration-or-alert-inbox-----404-not-fou

And my host name is full host name.

In exchange profiles my port is 50100 (J2EE PORT) (Not Changed)

1. In SMICM when I changed to port to 50100 (J2EE) then alert configuration

working, But My scenarios not working throwing error : System Error.

<b>Error Category XI_J2EE_MESSAGING_SYSTEM

Error Code HTTP_TRANSMISSION_ERROR</b>

2. In SMICM when I changed to port to 8001 (ABAP Port) then Alert configuration not working (Error : 404 Not Found), but my scenarios were working fine.

what would be the reason?

thx in advance,

Ansar.
