(102) RFC_ERROR_COMMUNICATION: Connect to message server host failed

Question

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

Answer 1

Now I've put in "193.183.156.17     PetJoh     PetJoh.afab.local" in Hosts -> rebooted -> but still can't ping exts0002 (or the fully resolved name to it) I can't ping the actual IP nr either.
I can, however use JCO java code like:
import com.sap.mw.jco.*;
public class R3Connect extends Object {
     JCO.Client mConnection;
     public R3Connect() {
          try {
               // Change the logon     information     to your     own     system/user
               mConnection     =
               JCO.createClient(
               "100",                                        // SAP client
               "rfcuser",                                   // userid
               "jakob",                                   // password
//               null,                                        // language
               "en",                                        // language
               "anb.af.hosting.emtab.com",               // application server host name
               "00");                                        // system number
               mConnection.connect();
               System.out.println(mConnection.getAttributes());
               mConnection.disconnect();
          } catch (Exception ex) {
               ex.printStackTrace();
               System.exit(1);
     public static     void main (String args[]) {
               R3Connect app =     new     R3Connect();
This works perfectly fine to connect, Why doesn't SLD?
