Connection on a transaction iView with SAPGUI

Hello all,

I've created a Transaction iView with SAP GUI for Windows on a EP6 SP11 and WebAS6.40

The System Alias has User Management configured to UIDPW and user mapping type admin,user.

The System has the following configuration:

Application Host: 172.16.18.25

Gateway Host: 172.16.18.25

Gateway Service: sapgw00

Logical System Name: sdrj20_D01_00

SAP Client: 110

SAP System ID (SID):D01

SAP System Number:00

Server Port:3600

System Type: SAP_R3

Everytime I've tried to connect on the transaction iView, I get this error:

connection partner broken

Component: NI(network interface)

Release: 640

Version: 37

Module: ninti.c

Line: 756

Method: NiPRead(172.16.18.25/3600, hdl3)

Return code: -6

System Call: recv

Counter: 1

Does anybody knows what this means?

Thanks,

Andre
