SAP .NET Connector Connection problems

[Former Member]

Hi all,

is anybody able help me solve this problem:

<b>Environment:</b>

SAP Preview 6.20 BSP on seperate WIN2K-server;access TCP/IP

Develop machine W2K SP4

GUI File Version 6402.2.3.978 Build 687100

Microsoft Visual Studio 2003 Version 7.1.3088

SAP .NET Connector 2.0.

librfc32 version 6403.3.69 in system folder

A c# program accessing the sap bapi Rfc_Get_System_Info raises an exception of this kind:

<i>Connect to message server failed

Connect_PM MSHOST=mdm1, R3NAME=BSP, GROUP=PUBLIC

LOCATION CPIC (TCP/IP) on local host

ERROR internal error

TIME Sat Jan 07 11:49:21 2006

RELEASE 640

COMPONENT MS (message handling interface, multithreaded)

VERSION 4

RC -101

COUNTER 6</i>

the exception is raised by the program instruction

<b>results = this.SAPInvoke("Rfc_Get_System_Info",new object[] );</b>

The proxy is created by

<b>m_connectString = this.mdm1_destination.ConnectionString;

infoProxy = new SAPInfoProxy(m_connectString);</b>

The destination object is customized by saplogon.ini OR manually. Result is always the same.

<b>Maybe these hints gives you an idea</b>:

When invoking SAPInvoke my firewall requests me to access the internet but i am working in a local network and all addresses are IPs.

The program is working fine on a WIN XP Client host ( V 5.1 Build 2600 xpsp2 )

Hi,

Try giving the Server names for destination. Or you can edit your C:\Windows\system32\drivers\etc\hosts file and add the corresponding IP address to the Server mapping. Disable your connection settings in IE. You should be able to get to the server without any exception.

Regards,

Siva

P.S: Award points if you find this useful.

Thanks for your answer but .....

the server name was set in the hosts file and there are NO connection settings in the IE.
