Frustrating to start Lotus Sametime Stmux Service

This Friday is a freaky day because suddenly after I’ve restarted our sametime server, all user can’t log in to sametime.
first things first, I was checked my windows firewall is ok, all open has been open. But when I’ve checked sametime service, i’ve seen stmux.exe (Sametime Community Multiplexor) was failed to running. I’ve already start manually but it failed to start.

Then I was check on sametime.log, I was found these messages :
” I Mux 19/Aug/11, 19:59:56 Listeners and CBR conflict!: Cannot route to port=80, ip=x.x.x.x (http server). exiting!”

That’s why stmux.exe (sametime services) was failed to run…

On the next step, I was go to server document – ports – internet ports – web tab and I was found on TCP/IP number is port 80. I thought may be this port cause stmux service problem, so I was changed these port to 8080 and magically stmux service is now running again.

Then in the next step I can sleep well and having dinner with my family
