(102) RFC_ERROR_COMMUNICATION: Connect to message server host failed

Hello,

I'm almost giving up on this...I've been messing with this for too long now...

I get this error message:

com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM

TYPE=B MSHOST=exts0002 GROUP=PUBLIC R3NAME=ANB MSSERV=sapmsANB PCS=1 ERROR hostname 'exts0002' unknown TIME

Tue Feb 14 16:40:02 2006 RELEASE 640 COMPONENT NI (network interface) VERSION 37 RC -2 MODULE ninti.c

LINE 332 DETAIL NiPGetHostByName2: hostname 'exts0002' not found SYSTEM CALL gethostbyname_r COUNTER 1

I try to get the flightlist demo to work. I've put in "sapmsANB 3600/tcp" in services file locally in my machine (I'm using Sneak Preview SP11).

I've also done everything in "/people/sugree.phatanapherom/blog/2005/08/14/configuring-sld-in-sneak-preview-sap-netweaver-04-sneak

I've done everything possible to get this to work, but no luck.

What is wrong here?, please help

    When your machine goes to call exts0002 it can't resolve that name. What happens if you try to ping exts0002 from the machine where the JCo call will be executed? This should resolve. You may have to modify your host file. Also, as a best practice you should get in the habit of calling machines by their fully qualified domain name. SAP logon tickets rely on this.
