Problem in JCO Connection

[Former Member]

I have installed SAP Netweaver Sneak Preview SP18 and getting the following error message while configuring the JCO. Any clue????

com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=uucf05h0 GROUP=PUBLIC R3NAME=GHD MSSERV=sapmsGHD PCS=1 ERROR service '?' unknown TIME Tue May 29 16:17:50 2007 RELEASE 640 COMPONENT NI (network interface) VERSION 37 RC -3 COUNTER 1

Hi there,

1 - Is there a entry at file service under c:\windows\system32\driver\etc with the following name "sapmsGHD"?

2 - Is there a PUBLIC logon group at the backend?

Regards,

Luciano

Hey Saket,

that means one of two things:

1. GHD is down

2. Your SLD configuration is incorrect

Please award some points:-)
