connection problem when use .net connection in VS.net

Hi, I installed .net connector 2.0 in VS.net 2003, when I try to connect a SAP R/3 server in "server explorer", I got the following error message.

-


from here----


Connect to SAP gateway failed

Connect_PM GWHOST=xx.xx.xx.xx, GWSERV=sapgw00, ASHOST=xx.xx.xx.xx, SYSNR=00

LOCATION CPIC (TCP/IP) on local host

ERROR partner not reached (host bscndev, service 3300)

TIME Thu Jan 27 12:22:18 2005

RELEASE 620

COMPONENT NI (network interface)

VERSION 36

RC -10

MODULE ninti.c

LINE 972

DETAIL NiPConnect2

SYSTEM CALL SO_ERROR

ERRNO 10061

ERRNO TEXT WSAECONNREFUSED: Connection refused

COUNTER 1

end of here----


The DestinationType in properties of this server is set as "SAPLOGON.INI based Logon Settings". There is no problem if I connect the R/3 server using sapgui.

I tried some other R/3 systems, both of access from VS.net and sapgui were OK.

Are there anybody have some ideas regarding to this problem? Also, I have no idea why sap logon from VS.net will connect to SAP gateway?

Thanks and best regards,

Jin Shen

    Might be the system is not configured as usual. RFC-based communication allways needs a so called Gateway process, that is normally automatically running on each application server. SAPGUI doesn't need it.
