Connect to message server host failed


we have created the technical system with message server port as 3600

we have used the logon Group SPACE which is existing in R/3(tcode smlg) while creating technical system.

Mantained the same port in the services file as

sapmsSRD 3600/tcp #message server port

sapgw00 3300/tcp #SAP Gateway Port

sapdp00 3200/tcp #SAP DispatcherPort

from SAP R/3 we have checked the Message server status (tcode sm51) showing no errors

and finally restarted the complete machine, inspite of all we are getting the this error :$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST= GROUP=SPACE R3NAME=SRD MSSERV=sapmsSRD PCS=1 ERROR partner 'srddev1:sapmsSRD' not reached TIME Sat Jun 19 18:16:32 2010 RELEASE 701 COMPONENT NI (network interface) VERSION 38 RC -10 MODULE nixxi.cpp LINE 2835 DETAIL NiPConnect2 SYSTEM CALL connect ERRNO 111 ERRNO TEXT Connection refused COUNTER 1

Please suggest the way to take it ahead

Hi vijay,

telnet: connect to address Connection refused
telnet: Unable to connect to remote host: Connection refused

Firstly, can you confirm are you able to login to SRD system using SAP GUI.

If yes, then it is confirm , there is some firewall blocking between 2 system.

Then for this issue you have to get the solution from your network team.

Show them this error they will understand this easly.

If no, you are not able to login to SRD system using SAP gui.

Then you have to start SAP first.
