MLLP rejects remote connections

[Kish]

Hi,

I have developed a interface which forwards the ORM order messages to
the lab system from SCM system.

The main problem is with the MLLP, BizTalk receives and process the
order messages when sent from the same machine i.e., using the
MLLPSend tool on a given port number. But unfortunately BizTalk
(BTAHL7) rejects any connections which are made from outside the
server i.e., when the messages are sent from different machine or from
the SCM system itself.

The error msg I can see from the sending computer is "Can't connect to
host 10.17.125.1 on port 13000: No connection could be made because
the target machine actively refused it".

I'm totally stuck with this problem, could someone help me with this
please?

Thanks in advance...

Kish,
It seems unlikely to me (having physically seen it work) that this
could be a problem with the MLLP Adapter.

1) Check to see that you have configured the MLLP Adapter to listen on
that address, in the Receive Location, make sure 10.17.125.1 is the
receive IP Address
2) Make sure that you are listening on that address, Open a command
prompt and type:
netstat -na | findstr 13000
3) Make sure that you don't have a firewall blocking that port

Hi Tom,

Thank you, well I have checked the IP address and the port number, its
not been blocked by the firewall and the port is in the listening
mode.
Infact, if I disable the listening port in the biztalk and run the
mllpreceive tool listening to that port I can clearly see the incoming
message.

Would there be an issue with the permissions on the biztalk side of
things which is rejecting the connections from other systems.

Thank you,
Kishore

Can you run your DOS window under the same userid that BizTalk is running
under and see if you experience the same behavior?

Hi,
I did check the user under which BizTalk is running and tried to run
the DOS promt and it works just fine including the MLLP tools.
For some reason the mmc/biztalk is rejecting the connections made from
network traffic on the listed port.

Thank you,
Kishore
